Department of Mechanical... extrusion(ECAE) process at a temperature of 200°C using route A, with a constant ram speed of 30 mm/min through a die angle of 90° between the die channels for as many as 6 passes. The experiments were......
Bulk Al–Al3Zr composite prepared by mechanical alloying and hot extrusion for high-temperature applicationsE.Pourkhorshid1,M.H.Enayati1,S.Sabooni1,F.Karimzadeh1,M.H.Paydar21. Department of Materials... composite was prepared by a combination of mechanical alloying(MA) and hot extrusion processes. Elemental Al and Zr powders were milled for up to 10 h and heat treated at 600℃ for 1 h to form stable......

归因于合金化和细晶强化的综合作用. 关键词:镁合金；挤压比；组织；拉伸性能 中图分类号:TG146.2 文献标志码:A Effects of extrusion ratio.... School of Economic and Management, Henan Polytechnic University, Jiaozuo 454000, China) Abstract: Mg-6Zn-1Y-1Ce alloy bars with diameters of 14 mm, 12 mm and 10 mm were prepared by extrusion from......
conditions were investigated. Microstructure analysis indicated the remarkable grain refinement by extrusion, as well as notable reductions in volume fraction and size of precipitate phases. As compared... by extrusion decreased from 1.68 to 0.32 mm/year. The reasons for the enhanced corrosion resistance were mainly attributed to the decreased volume fraction and Volta potential of the precipitate phases......
and Engineering, Harbin University of Science and Technology摘 要:Magnesium(Mg) alloy AZ31 was produced by continuous variable cross-section direct extrusion(CVCDE.... The recrystallization in Mg alloy AZ31 produced by CVCDE with 2 interim dies was more complete than that produced by conventional extrusion(CE) and CVCDE with 1 interim die, and the grains were finer and more......
A Finite Element Simulation of NiTi Alloy during Equal Channel Angular Extrusion王伟之,程先华School of Mechanical Engineering, Shanghai Jiaotong University摘 要:Particle tracking method is given to analyze the equal channel angular extrusion (ECAE) process of NiTi alloy in non-isothermal condition. The distribution of effective strain, effective stress......
Effect of Extrusion Temperature on the Microstructure and Mechanical Properties of Mg–5Al–2Ca AlloyKun Su,Kun-kun Deng,Fang-jun Xu,Kai-bo Nie,Li Zhang,Xiao Zhang,Wei-jian LiCollege of Materials... of Al2Ca particles are influenced evidently by extrusion temperature. Unlike previous reports, the intensity of basal texture increases with increasing extrusion temperature, and the reasons are analyzed......
