| 1 | Adhesion Wear on Tool Rake and Flank Faces in Dry Cutting of Ti-6Al-4V显示文摘Titanium alloys are very chemically reactive and,therefore,have a tendency to weld to the cutting tool during machining.The deterioration in the tool life caused by adhesion is a serious problem when titanium alloys are cut using carbide tools.The chemical reactivity of titanium alloys with carbide tool materials and their consequent welding by adhesion onto the cutting tool during dry cutting leads to excessive chipping,premature tool failure,and poor surface finish.In the present study,dry turning and milling tests were carried out on Ti-6Al-4V alloys with WC?Co carbide tools.The adhesion on the tool rake and flank face was explored,the adhesive joint interface between the workpiece materials and tools were observed.SEM observation showed that adhesion can be observed both on the rake and the flank face,and was more pronounced in rake face than in flank face.There was evidence of element diffusion from the tool rake face to the adhering layer(vice versa) through the adhesive joint interface,which leads to the tool element loss and microstructure change.While the adhering materials at the flank face can be easily separated from the joint interface owing to the lower temperature and less pressure at the flank face,the adhesive wear attack results in an abrasive wear in the flank face.Moreover,adhesion is more notable in turning than in milling.The proposed research provides references for studying the adhesion between the workpiece materials and the tools,the adhesion mechanisms and their effect on the tool wear. | DENG Jianxin LI Yousheng ZHANG Hui | 2011 | Chinese Journal of Mechanical Engineering2011，24，6： | 2 |

| 8 | High-yield Cultivation Techniques of Stevia rebaudiana(Bertoni) Hemsl. in Gannan Area of Jiangxi Province显示文摘In order to expand the production of Stevia rebaudiana( Bertoni) Hemsl.,the main points of high-yield cultivation techniques of a two-year-old stevia cultivar Shoutian No. 3 in Gannan area of Jiangxi Province were summarized: cutting and transplanting in early spring; fine management,applying more basic and additional fertilizers and retaining stubbles two times in summer,retaining roots for seeding in late autumn,and mulching membrane for safe overwintering in winter. This study will provide practical guidance for the planting of S. rebaudiana in Ganzhou,Jiangxi Province. | Wentao SHENG Jianlan DENG Xuewen CHAI Yousheng RAO Baoan ZHOU | 2018 | Asian Agricultural Research2018，10，6： | 0 |
| 9 | Reliability Analysis for Retaining Pile in Foundation Pit Based on Bayesian Principle显示文摘Moso bamboo has the advantages of high short-term strength and reproducibility,appropriating for temporary supporting structure of shallow foundation pit.According to the displacement of the pile top from an indoor model test,the reliability of the supporting effect of the moso bamboo pile was analyzed.First,the calculation formula of reliability index was deduced based on themean-value first-order second-moment(MVFOSM)method and probability theory under ultimate limit state and serviceability limit state.Then,the dimensionless bias factor(the ratio of the measured value to the calculated value)was introduced to normalize the displacement.The mathematical characteristics of the displacement were estimated and optimized based on Bayesian theory.Finally,taking 2.5 as the design reliability index,the effect of safety factor,tolerable limit displacement,and the ratio of the ultimate limit displacement to the tolerable on reliability index was analyzed.The results show that the safety level of the supporting pile can be increased by 1–2 levels when the safety factor increases by 0.5.When the coefficient of variation of tolerable limit displacement is less than 0.3,the safety factor can be 2–2.5.And the ratio of the ultimate limit displacement to the tolerable has a great influence on the reliability index,when the soil conditions is well,the ratio can be 1.2–1.3. | Yousheng Deng Chengpu Peng Jialin Su Lingtao Li Liqing Meng Long Li | 2022 | Computer Modeling in Engineering & Sciences2022，，2： | 0 |
