摘要
结合国内外对镁合金塑性变形过程中孪生行为的研究进展,阐述了孪生的晶体学以及几何位向学;分析了孪晶与孪晶之间以及孪晶与滑移之间的相互作用;探讨了影响孪生的几方面因素,包括应变路径、形变温度、应变速率、晶粒尺寸以及晶粒取向。
Combining the domestic and overseas development of plastic deformation research in magnesium alloy,the crystallology and geometry of twinning were overviewed.Then,the interaction between twins and between slip dislocations and twins were analyzed.The effects of several factors on the twinning,including strain path,temperature,strain rate,grain size and crystal orientation,were emphasized.
