概述目前,金属材料的超塑性现象及其使用价值已越来越受到冶金学家、材料科学家和工业界的重视。具有超塑性的金属与合金正在不断地为人们所发现,到目前为止,不论是钢铁材料,还是有色金属材料(其中包括轻、重、稀、贵金属),都发现在一定的组分、组织结构和一定的变形条件下显示出超塑性。现在,也许可 Overview At present, the superplasticity of metal materials and their value has been more and more attention by metallurgists, material scientists and industry. Metals and alloys with superplasticity are constantly being discovered, so far, whether it is steel, non-ferrous materials (including light, heavy, rare, precious metals), have found that in a certain composition, structure And under certain deformation conditions show superplasticity. Now, maybe
