摘要

中文摘要: 为研究不同热处理工艺对34CrNi3Mo铸钢力学性能的影响，对比了“喷水淬火+高温回火”、“油淬+高温回火”、“双液淬火+高温回火”和“双液淬火（水-油）+两次高温回火”四种热处理工艺条件下34CrNi3Mo铸钢的力学性能。结果表明：采用“喷水淬火+高温回火”处理的试样不仅比“油淬+高温回火”处理的试样强度好、硬度高，而且塑性和冲击韧性也更好。当对铸件进行“双液淬火（水-油）+高温回火”后，可以实现铸件外强内韧的特性；双液淬火（水-油）后两次高温回火会使铸件的强度、硬度更高，但塑性、韧性下降。

Abstract

Abstract: In order to research the effects of different heat treatment processes on mechanical properties of 34CrNi3Mo cast steel

the mechanical properties were compared in the condition of four kinds of heat treatment technologies which were “water spraying quenching with high temperature tempering”

“oil quenching with high temperature tempering”

“dual fluid quenching (water-oil)with high temperature tempering” and “dual fluid quenching with two times high temperature tempering”. The results show that not only the casting processed by “water sprying quenching with high temperature tempering” has better strength and hardness than that processed by “oil quenching and high temperature tempering”

but also has greater plasticity and impact toughness. The characteristics of strong external part and toughness internal can be achieved with “dual fluid quenching with high temperature tempering”. Dual fluid quenching (water-oil) and then twice high temperature tempering make the strength and hardness of the casting higher

but the plasticity and toughness get decline.
