Abstract: The crystallographic nature of initial isothermal phase transformation in Cu-26Zn-4Al (wt-%) was investigated. The kinetic transforma- tion curve, morphology, crystal structure, substructure, orientation relationship and twin relationship of bainite plates have been studied by means of optical and transmission electron microscopy. The experimental results showed that the characteristics of initial 8→bainite transformation are not exactly consistent with that found in martensite transformation, for example, orientation relationship between matrix and bainite does not exist in martensite transformation.

Key words: bainite transformation, Cu-Zn-Al alloy, orientation relationship
