| 2 | Modelling the Effect of Initial Grain Size on Dynamic Recrystallization Using a Modified Cellular Automata and a Adaptive Response Surface Method显示文摘A modified cellular automata (CA) model of dynamic recrystallization (DRX) and a flow stress-based nucleation parameter identification method have been developed.In the method,the modified CA model,which takes the role of deformation degree on nucleation behavior into consideration,is coupled with an adaptive response surface model (ARSM) to search for the optimum nucleation parameter.The DRX behavior of an oxygen free high conductivity (OFHC) copper with different initial grain sizes has been taken as an example to validate the model.Good agreement is found between the simulated and the experimental results,which demonstrates that the new method can effectively improve the simulation accuracy. | Zhaoyang Jin Zhenshan Cui | 2010 | Journal of Materials Science & Technology2010，26，12： | 6 |
| 3 | Application of orthogonal experimental design and Tikhonov regularization method for the identification of parameters in the casting solidification process显示文摘The inverse heat conduction method is one of methods to identify the casting simu- lation parameters. A new inverse method was presented according to the Tikhonov regularization theory. One appropriate regularized functional was established, and the functional was solved by the sensitivity coeffcient and Newton-Raphson iteration method. Moreover, the orthogonal experimental design was used to estimate the ap- propriate initial value and variation domain of each variable to decrease the number of iteration and improve the identification accuracy and effciency. It illustrated a detailed case of AlSi7Mg sand mold casting and the temperature measurement ex- periment was done. The physical properties of sand mold and the interfacial heat transfer coeffcient were identified at the meantime. The results indicated that the new regularization method was effcient in overcoming the ill-posedness of the inverse heat conduction problem and improving the stability and accuracy of the solutions. | Dashan SUI Zhenshan CUI | 2009 | Acta Metallurgica Sinica(English Letters)2009，22，1： | 4 |
| 4 | xperimental investigation on cumulative propagation of thin film buckling under cyclic load显示文摘As instrument technology is needed for rapid determination of the smaller,thinner and lighter specimens,more stringent demands are related to thin films such as micro-electro-mechanical systems(MEMS),dielectric coatings and electronic packaging.Therefore,the requirement for testing platforms for rapidly determine the mechanical properties of thin films is increasing.Buckling of a film/substrate system could offer a variety of applications,ranging from stretchable electronics to micro-nanoscale metrology.In this paper,a fatigue-loading device has been designed to make the cyclic loading available for investigating the cumulative propagation of thin film buckling.The straight side buckling of thin compressed titanium film with the thickness of 50 nm deposited on organic glass substrates is investigated by using an optical microscope.The cumulative buckling propagation under the cyclic loading of a sequence of peak compression with the frequency 1 Hz is recorded by CCD camera.The buckling extension lengths are calculated by digital image measurement technology. | WANG ShiBin JIA HaiKun LI LinAn SUN Heng CUI DiQiang GUO ZhenShan XUE XiuLi | 2011 | Science China(Technological Sciences)2011，54，6： | 4 |
| 5 | Integrated Modelling of Microstructure Evolution and Mechanical Properties Prediction for Q&P Hot Stamping Process of Ultra‑High Strength Steel显示文摘High strength steel products with good ductility can be produced via Q&P hot stamping process,while the phase transformation of the process is more complicated than common hot stamping since two-step quenching and one-step carbon partitioning processes are involved.In this study,an integrated model of microstructure evolution relating to Q&P hot stamping was presented with a persuasively predicted results of mechanical properties.The transformation of diffusional phase and non-diffusional phase,including original austenite grain size individually,were considered,as well as the carbon partitioning process which affects the secondary martensite transformation temperature and the subsequent phase transformations.Afterwards,the mechanical properties including hardness,strength,and elongation were calculated through a series of theoretical and empirical models in accordance with phase contents.Especially,a modified elongation prediction model was generated ultimately with higher accuracy than the existed Mileiko’s model.In the end,the unified model was applied to simulate the Q&P hot stamping process of a U-cup part based on the finite element software LS-DYNA,where the calculated outputs were coincident with the measured consequences. | Yang Chen Huizhen Zhang Johnston Jackie Tang Xianhong Han Zhenshan Cui | 2020 | Chinese Journal of Mechanical Engineering2020，33，3： | 3 |
| 6 | Review on modeling and simulation of microstructure evolution during dynamic recrystallization using cellular automaton method显示文摘The macro-mechanical properties of metal and alloy are largely depended on their chemical composition and microstructures resulting from the complicated processing and heat treatment history in industrial production. During these thermoplastic processes, dynamic recovery, dynamic recrystallization, static recovery and static recrystallization are the key microstructural evolution mechanisms. Accurate prediction and precise control of the microstructural evolution are of great importance for designers to achieve excellent mechanical properties for metals and alloys through hot working. Up to date, dynamic recrystallization has been recognized as a powerful mechanism for grain refinement. In-depth understanding of the microstructural evolution of dynamic recrystallization and furthermore to accurately predict and control the microstructure evolution during dynamic recrystallization process has become a research focus in the field of plastic processing. Cellular automaton(CA) method has been commonly employed to simulate the microstructure evolution of dynamic recrystallization due to its unique advantages,for example, it is easier to represent topological features and more realistically reflect the grain boundary migration process. In this paper, the basic ideas and characteristics of the CA method are briefly introduced. The physical mechanisms of dynamic recrystallization are summarized. Meanwhile, the state-of-the-art overview of the CA method of simulating the DRX process is introduced. Furthermore, this paper points out several problems that need to be solved urgently and prospects the development trend of the CA method for simulating the microstructure evolution in dynamic recrystallization. | ZHU HuaJia CHEN Fei ZHANG HaiMing CUI ZhenShan | 2020 | Science China(Technological Sciences)2020，63，3： | 3 |
| 7 | Finite element simulation of stretch forging using a mesh condensation method显示文摘In order to reduce the computation time of finite element simulations of stretch forging process,a mesh condensation method is presented and applied to a three-dimensional rigid-viscoplastic finite element program.In this method,a conventional mesh for the whole zone of a workpiece is condensed to a computational mesh for the active deformation zone.Two vital problems are solved,which are automatic construction of the computational mesh and treatment of interfaces between the deformation zone and the rigid zone.The mesh condensation method is compared with conventional finite element method by simulations of a six-bite stretch forging process.Some simulation results including forging load,temperature distribution and effective strain distribution are illustrated.The efficiency and accuracy of this method are verified. | CHEN Wen & CUI ZhenShan National Die & Mold CAD Engineering Research Center,Shanghai Jiao Tong University,Shanghai 200030,China | 2010 | Science China(Technological Sciences)2010，53，1： | 3 |
| 8 | Finite element modelling on microstructure evolution during multi-pass hot compression for AZ31 alloys using incremental method显示文摘Based on the principle of piecewise linearization, the incremental forms of microstructure evolution models were integrated into the thermo-mechanical coupled finite element(FE) model to simulate nonlinear microstructure evolution during multi-pass hot deformation. This is an unsteady-state deformation where dynamic recrystallization(DRX), meta-dynamic recrystallization(MDRX), static recrystallization(SRX) and grain growth(GG) take place during hot deformation or deformation interval. The distributions of deformation and microstructure for cylindrical AZ31 sample during single-pass and double-pass hot compressions were quantitatively calculated and compared with the metallographic observation. It is shown that both the deformation and microstructure are non-uniformly distributed due to the presence of friction between the die and the flat end of sample. The average grain size and its standard deviation under the double-pass hot compression are slightly smaller than those under single-pass compression.The simulated average grain sizes agree well with the experiments, which validates that the developed FE model on the basis of incremental forms of microstructure evolution models is reasonable. | Zhaoyang Jin Kai Yin Kai Yan Defeng Wu Juan Liu Zhenshan Cui | 2017 | Journal of Materials Science & Technology2017，33，11： | 3 |

| 15 | Catalytic transfer hydrogenolysis of C–O bonds in lignin model compounds without arene hydrogenation显示文摘The shortage of resources and the destruction of the environment have caused serious resource and environmental problems shared by all countries around the world. As a ubiquitous renewable resource, biomass has great prospects for replacing fossil energy and attracted attention from the society. The use of catalytic approach to transform biomass into high-value chemicals is an effective way to use biomass efficiently. In this work, Nisupported catalysts has been developed for the selective cleavage of C–O bonds in lignin model compounds with 2-propanol as the hydrogen source solvent. Among these catalysts, it was indicated that zirconium phosphate(Zr P)-supported Ni catalysts were highly efficient and recyclable for alkyl-aryl ether(α-O-4 and β-O-4) cleavage in lignin model compounds. The further investigation demonstrated that the transfer hydrogenolysis of the C–O bond is highly selective, which afforded phenols and aromatics as dominant products without the products arising from hydrogenation of aromatic rings. Through a series of characterization of the catalyst, it was demonstrated that the medium strong acid sites of the Zr P support promoted the cleavage of alkyl-aryl ethers(α-O-4 and β-O-4),and Br?nsted acid sites favored for achieving high selectivity toward C–O bond cleavage. Additionally, Ni(0) sites on the Zr P catalysts were responsible for the catalytic transfer hydrogenolysis. | Kai Cui Xiuge Zhao Qingpo Peng Honghui Gong Xinjia Wei Jiajia Wang Manyu Chen Zhenshan Hou | 2022 | Green Chemical Engineering2022，3，1： | 1 |
