| 1 | Experimental Investigation and Numerical Simulation of the Grain Size Evolution during Isothermal Forging of a TC6 Alloy显示文摘Hot compression was conducted at a Thermecmaster-Z simulator, at deformation temperatures of 800~1040℃, with strain rates of 0.001~50 s-1 and height reduction of 50%. Grain size of the prior α phase was measured with a Leica LABOR-LUX12MFS/ST microscope to which QUANTIMET 500 software for image analysis for quantitative metallography was linked. According to the present experimental data, a constitutive relationship for a TC6 alloy and a model for grain size of the prior α phase were established based on the Arrhenius' equation and the Yada's equation,respectively. By finite element (FE) simulation, deformation distribution was determined for isothermal forging of a TC6 aerofoil blade at temperatures of 860~940℃ and hammer velocities of 9~3000.0 mm/min. Meanwhile, the grain size of the prior α phase is simulated during isothermal forging of the TC6 aerofoil blade, by combining FE outputs with the present grain size model. The present results illustrate the grain size and its distribution in the prior α phase during the isothermal forging of the TC6 aerofoil blade. The simulated results show that the height reduction, deformation temperature, and hammer velocity have significant effects on distribution of the equivalent strain and the grain size of the prior α phase. | Miaoquan LI, Shankun XUE, Aiming XIONG and Shenghui CHEN State Key Laboratory of Solidification Processing, School of Materials Science and Engineering, Northwestern Polytechnical University, Xi’an 710072, China | 2005 | Journal of Materials Science & Technology2005，21，2： | 3 |
| 2 | Surface Construction System of the Airfoil Blade Based on B-spline显示文摘According to the construction principle of B-spline, a formula of surface construction for airfoil blade with the given points has been derived. Meanwhile, the surface construction system for airfoil blade in practice as well as menus for the system have been constructed with the help of the commercial software AutoCAD R14). The result in this paper is helpful for CAD/CAM of airfoil blades. | XIONG Aiming LI Xiaoli XUE Shankun LI Miaoquan | 2000 | International Journal of Plant Engineering and Management2000，5，4： | 0 |
