摘要
研究了ＣｕＺｎＡｌ合金在Ｍ（马氏体相）与β＿１（母相）共存状态的时效．结果表明，时效后有台阶出现，台阶实质上是Ｍ稳定化产生与消除共同作用的结果．随时效时间的延长，台阶变宽．台阶宽度还与Ｍ及β＿１相的相对含量有关．
CuZnAl alloy′s aging in M-phase and β_1-phase mixture state was investigated in this ar-ticle．It is showed that plateau will appearafter aging．In essence，plateau is the syntheticresult of the formation and elimination of martensite stabilization；plateau widens with in-creasing age time． Plateau width also has relations with the relative amount of M－and β_1-phase．
