研究了粗晶7475铝合金在多向热压缩条件下的晶粒细化。结构变化的特点是由于在各个方向上的微剪切带的频繁发展的晶粒破碎，其次是增加其数量和取向差，并最终在高应变的新晶粒的演变。(C)2004由Elsevier Ltd.代表Acta Materialia Inc.出版。
Grain refinement taking place in a coarse-grained 7475 Al alloy was studied in hot multidirectional compression. The structural changes are characterized by grain fragmentation due to frequent development of microshear bands in various directions, followed by increase in their number and misorientation and finally evolution of new grains at high strains.
