密排六方金属的塑性变形

Plastic Deformation of Hexagonal Close-Packed Metals

摘要:

综述了密排六方金属可能的滑移和孪生变形方式。滑移面包括：（０００１）基面，（１１００）柱面和〈ｃ〉型及〈ｃ＋ａ〉型锥面。（１０１２）、（１１２１）和（１１２２）是其主要的孪生类型，在Ｔｉ和Ｚｒ中还可能出现（１０１１）、（１１２４）和（１１２３）型孪晶。进一步分析了塑变过程中滑移和孪生之间的关系。着重讨论了Ｔｉ和Ｚｒ的滑移方式与试验温度之间的关系，其滑移面开动按由易到难的排列顺序为：柱面、锥面和基面

Abstract:

The possible slipping and twinning modes in hop metals are summarized. The slipping plane includes (0000) hasal. (1100)prismatic plane and c-type. c+a-type Pyramidal plane. {1012}. {1121}and {112 2}are the primary twinning modes. {1011} {1124}and {1123}type twins are possible to appear in Ti and Zr.The relationship between slipping mode and the tasting temperature in Ti and Zr is discussed. The slipping planes arranged in order of ease of operation are prismatic.pyramidal and hasal planes.
