摘要
本文综述了纳米和超细晶金属材料的退火强化研究现状和发展趋势。本文关注致密纳米和超细晶材料的研究,首先介绍了电沉积纳米Ni、强塑性变形制得的超细晶金属钛和纯铝的退火强化的实验现象,随后综述了这一强化现象的微观机理,最后探讨了进一步的实验及理论分析的途径。
In this paper,annealing strengthening and the following work softening are reviewed for three nanostructured and ultrafine-grained metals,including electrodeposited nanocrystalline Ni,severe plastic deformation(SPD) treated Ti and Al.Three aspects of the researches are reviewed and discussed:(1) experiments,(2) mechanism analysis,(3) suggestions for further study.
