面向驱动桥壳再制造的塑性损伤研究
Plastic Damage Research for Drive Axle Housing Remanufacturing
摘要
Abstract
In order to study local area's plastic damage of waste drive axle housing and quantitative evaluate plastic deformation,a drive axle housing's body material-510L steel plate was taken as tensile test specimens. After Stretching these test specimens to different plastic deformations,by means of X-ray diffraction techniques,metal intelligent magnetic memory analysis techniques,and scanning electron microscope, the relationship among material's plastic deformation rate, X-ray signals and magnetic signals was evaluated comprehensively. Scanning electron microscope was used to observe crystal structure variation characteristics of different plastic deformation rates. The study demonstrates that the X-ray diffraction peak width can be used to quantitatively calculate material's plastic deformation rate at the stage of strain-hardening, the normal component of magnetic field Hp(y) is less.关键词
