从高温到室温都存在双相组织的(H1Cr25Ni13)合金是一个典型牌号。本文着重对其锻造塑性进行了研究,观察了不同温度下δ′铁素体的析出情况,对影响锻造塑性的机制因素作了分析讨论。推断出该合金锻造塑性的好坏是与钢中γ相与α′相组分的差别所决定,而与加热温度有着密切的关系。本文指出:应选择在奥氏体与铁素体组分在机械性能方面差别最小的温度下进行锻造。 (H1Cr25Ni13) alloy, which exists from high temperature to room temperature, is a typical grade. This paper focuses on the forging ductility, studies the precipitation of δ ’ferrite at different temperatures, and discusses the mechanism factors that influence the ductility of forging. It is deduced that the ductility of the alloy is determined by the difference between the γ phase and the α ’phase in the steel, which is closely related to the heating temperature. This paper states: Forging should be selected at a temperature at which austenite and ferrite components will have the least difference in mechanical properties.
