摘要
以Cr、Mo和V微合金化模具钢为对象,研究了淬火和回火温度对模具钢力学性能和显微组织的影响。结果表明,淬火温度为1 080℃时模具钢具有较好的硬度与冲击韧度。在1 080℃淬火580℃回火条件下,模具钢基体中大量弥散分布的纳米级V(C,N)、Cr23C6和Mo2C析出物,起到了有效的弥散强化作用。
The effects of heat treatment on microstructure and properties of die steel with Cr, Mo and V were studied. The resutls show that the hardness and impact toughness of the die steel are optimized when the quenching temperature is 1 080℃. The fine nano V（C, N）, Cr23C6 and Mo2C precipitates play a main effect to improve the mechanical properties of the die steel when the quenching temperature and tempering temperature are 1 080 ℃ and 580 ℃, respectively.
