Study on Austenitic Grain Growth for Heat Resisting Steel P91

Article Preview

Abstract:

According to the typical large-diameter thick-walled steel T/P91 (10Cr9Mo1VNb), during the hot working, there are dynamic recrystallization and grain growth. The influence of the samples at different hot treatment on the grain size and grain growth rate were obtained by the statistics of the grain size, The grain growth index under various heat treatment were compared, the mathematical model of the austenite grain growth law of P91 alloy steel was established.
