Study of the Mechanical and Physical Characters on the SiCp/Al Cutted Superficial Layer
Author(s): 
Pages: 47-50
Year: Issue:  3
Journal: JOURNAL OF WUYI UNIVERSITY(NATURAL SCIENCE EDITION)

Keyword:  SiCp/Al力学物理性能表面层硬度残余应力;
Abstract: 通过切削试验研究,从宏观和微观的角度探讨了SiCp/Al材料本身微观组织结构,切削力,切削温度等因素对已加工表面层硬度和表面残余应力的影响. 试验结果表明:已加工表面层硬度和残余应力是各种因素叠加作用的结果,最高硬度值出现在次表层,切削温度升高使表面具有拉应力和加工软化的倾向增大,表面层塑性变形增大使表面残余压应力和加工硬化的倾向增大.
