摘要
研究了航空发动机用 2 5Cr3MoA合金钢棒材热处理对其组织和性能的影响。主要研究结果如下 :电弧加电渣重熔冶炼的 2 5Cr3MoA钢组织均匀 ,纯净度高 ;其艾氏冲击功夏比冲击功没有对应关系 ;WS9- 6 0 0 1组别低温冲韧性最好 ;在 6 0 0℃以下仍保持较好的高温性能 ,4 0 0℃时该钢具有较高的高温疲劳强度。
This paper studies the effect of heat treatment of alloy-steel bar 25Cr3MoA on its structure and properties.The following results were obtained:alloy-steel bar 25Cr3MoA produced by the process of electric arc furnace(EAF) and electroslag remelting had homogeneous structure and high cleanness;no relationship between A KI and A KV was found;impact toughness for test group WS9-6001 at low temperature was the highest;25Cr3MoA had better high temperature properties below 600?℃ and high temperature fatigue strength at 400?℃.
