摘要
Abstract
By means of study and comparison on dynamic recrystallization behavior of high-Nb and low-Nb X80 pipeline steel, some conclusions were obtained:the high-Nb steel has the behavior of dynamic recrystallization at a higher temperature and a lower strain rate compared to the low-Nb steel. The dynamic recrystallization activation energy of the high-Nb and low-Nb pipeline steel are 342.95 Kj/mol and 306.02 Kj/moL High-Nb content can restrain the dynamic recrystallization of austenite and delay the transformation of stress -strain curve to become the type of dynamic recrystallization.Therefore.the terminated temperature of recrystallization is increased greatly.关键词
