摘要
通过正交设计试验和方差分析方法讨论了奥氏体化温度，形成贝氏体的等温温度及贝氏体的相对量对ＧＣｒ１５钢Ｍ／Ｂ复查组织的冲击韧性与硬度的影响．结果表明：贝氏体的相对量显著影响复相组织的冲击韧性及硬度，而奥氏体化温度和形成贝氏体的等温温度则对其影响不大．
This paper deals with the effeCts of austenitizing temperature, bainite-forming isothermaltempelature and relative quantity of bainite on the impact toughness (αk) and hatdness (HRC)of GCr15 steel with M/B duplex edrostructure by means of the orthogonal test and varianceanalysis. The results show that the impact toughness and hardness of the duplex microstructure are remarkably by the relative quantity of bainite, but not obviously by the austenitizing temperatare and isothrmal temperature.
