3)  nickel and chromium-containing steel slab
镍铬低合金钢坯
4)  low chromium tool steel
低铬合金工具钢
5)  chromium-nickel low carbon stee
铬-镍低碳合金钢
6)  low alloy steel containing aluminium and niobium
含铝、铌低合金钢
1.
The transformation kinetics of pearlitic→austenite in deformed low alloy steel containing aluminium and niobium with deformation was investigated by the methods of DSC,through which the relationship curve between the volume fraction of transformation and the temperature were drawn,and the change of transformation active energy with the volume fraction of transformation was obtained.
本文采用DSC法研究了形变含铝、铌低合金钢组织中珠光体→奥氏体的相变动力学。
