在晶体材料中存在着孪生现象,这是大家熟知的。孪生的结果,生成挛晶。孪晶由于其形成机制不同,分为机械挛晶(或称形变挛晶)、生长孪晶和退火孪晶等。关于机械孪晶,它作为变形的一种机制,研究得很多,而对退火孪晶的研究则较少。产生退火孪晶是面心立方金属的一大特征。关于面心立方金属在高温退火过程中形成退火孪晶,以及
It is well-known that twinning occurs in crystalline materials. The twin result is twins. Twins due to their different mechanisms of formation, is divided into mechanical twisting (or deformation twins), growth twins and annealing twins. Regarding mechanical twins, it has been studied a lot as a mechanism of deformation and less studied on annealing twins. Annealing Twins are a major feature of face-centered cubic metals. About Face Cube Metals form annealing twins during high temperature annealing, as well
