    The stabilization of the thermoelastic martensite in a rapidly solidi-fied Cu-Zn-Al alloy is believed to be an atomic configuration from ordering todisordering, and the transition of martensite structure from M18R to N9R (b/a=1/3~(1/2)). This is dependent upon the intrinsic decomposition tendency of the marten-site.
