β' Cu-Zn-Al 合金中温区等温转变的研究

Isothermal Tranformation within the Medium Temperature Range in a β′CuZnAl Alloy

利用光学显微镜及透射电镜考察了β′Ｃｕ－Ｚｎ－Ａｌ合金中温区等温转变，发现其初期形成的α１内部具有完整的层错亚结构，其体转变激活能约为Ｚｎ扩散激活能的１／３．

The lsothermal transformation within the medium temperature range in a β′CuZnAl alloy is investigated by optical microscope and TEM. The Bainitea 1formed at early stage has stacking fault substructure and its overall activiation energy is only one third of the diffusional activiation energy of zinc.
