3.5%Ni低温用钢形变奥氏体再结晶规律及连续冷却转变行为的研究

RECRYSTALLIZATION OF DEFORMED AUSTENITE AND CONTINUOUS COOLING TRANSFORMATION IN 3.5% Ni STEEL FOR CRYOGENIC USE

本文主要对3.5%Ni低温用钢形变奥氏体的再结晶行为和各工艺参数对连续冷却过程中的相变温度、相变过程及产物形貌的影响规律等进行了较系统的实验研究及分析讨论,尤其对该钢与普碳钢及微合金化 HSLA 钢的相应规律的对比给予了较多的注意。

Experimental investigations and systematic analysis have been carried out on recrystallizationbehavior of deformed austenite and on the effect of technological parameters upon phase tran-sition temperature,transferomation process and morphology of microstructure produced duringcontinuous cooling in the 3.5% Ni steel.Special attention has been paid to the comparisonbetween the case of 3.5% Ni steel and plain carbon or microalloyed steels.
