摘要
研究了预淬火马氏体对 Ｇ Ｃｒ１５ 钢马氏体／ 下贝氏体（ Ｍ／ Ｂ） 复合组织及性能的影响。试验结果表明，通过 Ｍｓ 以下适当温度的预淬火，获得的 Ｍ／ Ｂ 复合组织具有更优的机械性能。
Effect of pre quenching martensite on the properties of M/B duplex microstructure was studied. The experimental results showed that the M/B duplex microstructure obtained by pre quenching at suitable temperature under M s point was of better mechanical properties.
