形变对低碳马氏体力学性能的影响张伟强，李智超，董允，于维成，张剑（阜新矿业学院）（中国科学院沈阳金属研究所）１前言低碳低合金钢具有较优的热加工工艺性能，在淬火及回火后得到板条马氏体，具有较高的强度和较好的塑性与韧性。因此，在机械制造行业中得到广泛的应...
The effect of cold deformation on microstructure and mechanical properties is investigated in quenched and low-temperature-tempered 2 0 MnV and20 MnVB steel In the result, with strain rate increaseing the low carbon and low alloy steel has an increase in strength and a decrease in ductility,while the cycle number of fatigue fracture is also remarkably ralsed. Strengthening of steel is related to dislocation increment in lath martensite and the decrease of dislocation movability,which also increases the cycle number for fatigue fracture.
