【摘要】 应用ForMaster Digital相变膨胀仪测定了P2 0塑料模具钢奥氏体的等温转变动力学图。等温转变的组织结构研究表明 ,奥氏体在河湾区上部转变为珠光体 ,在贝氏体区转变为粒状贝氏体和下贝氏体

【Abstract】 The time temperature transformation (TTT) diagram has been got by ForMaster-Digital phase transformation thermal expansion instrument. The study on TTT structure indicated that the austenite transferred into pearlite at upside of austenite bay in TTT diagram and transferred into granular bainite and lower bainite in bainite transformation zone.
