| 摘 要： | 本文用扫描隧道显微镜（ＳＴＭ）在天气中研究了Ｃｕ－２７．２ｗｔ．％Ｚｎ－４．７ｗｔ．％Ａｌ合金中的贝氏体的精细结构，并与透射电镜（ＴＥＭ）及扫描电镜（ＳＥＭ）下的形态进行了比较，发现Ｃｕ－Ｚｎ－Ａｌ合金中贝氏体是由亚片条或亚单元组成，亚单元由超亚单元构成，进而为贝氏体相变机制的再认识提供了重要的实验基础，并在此基础上提出Ｃｕ－Ｚｎ－Ａｌ合金中贝氏体的形成模型。

| Abstract: | The fine structure of bainite in Cu-27.2wt.%Zn-4.7wt.%Al alloy has been studied with Scanning Tunnel-ing Microscope(STM)in air.Comparing with the TEM and SEM observation,it has been discovered that thebainite structute in Cu-Zn-Al alloy is composed of subplates.The subplate can be further divided into subunits,and then to ultra-subunits.The results strongly indicate a sympathetic nucleatiom mechanism of bainite reac-tion. |
