摘要
本文主要分析了冷却速度与加热温度对45钢力学性能、显微组织产生的影响。研究结果指出,如果热处理的加热温度不同,会导致45钢硬度性能与显微组织发生改变。因此,热处理的温度不宜过低也不能过高,比较适合的温度为840℃。此外,不同冷却速度也会影响45钢。如果冷却速度发生改变,45钢组织也会出现变化,进而改变45钢的性能。
In this paper, the effects of cooling rate and heatingtemperature on the mechanical properties and microstructure of45 steel were analyzed. The research results indicate that if theheating temperature of the heat treatment is different, the hardnessand microstructure of the 45 steel will be changed. Therefore, thetemperature should not be too low heat treatment can not be toohigh, more suitable for the temperature of 840. In addition, thedifferent cooling rate will affect the 45 steel. If the cooling ratechanges, the 45 steel structure will change, and then change theperformance of the 45 steel.
