The result is that the tempering brittleness is smaller after tempering when the lower bainite instead of the plate martensite at the grain-boundary of the patent in the process of quenching. Observation of morphology of the plate martensite were performed.
实验结果表明:采用等温淬火使钢的晶界优先生成晶界下贝氏体代替晶界片状马氏体,经低温回火后钢的回火脆性相对比较小。
