摘要
研究了Ｃｒ１２Ｍｎ５Ｎｉ４Ｍｏ３Ａｌ沉淀硬化不锈钢弹簧低周疲劳性能和疲劳断口，指出在５２０℃时效时，由δ铁素体析出的大片状Ｊ相和α＇相诱发疲劳裂纹是降低疲劳寿命的主要因素；在３００℃时效处理可大幅度提高疲劳寿命。
Low cycle fatigue properties and fracture of spring made of precipitation hardening stainless steel Cr12Mn5Ni4Mo3Al are investigated. It is indicated that J and α' phase, separated form δferrite during aging at 520℃, induced fatigue crack is main factor decreaseing fatigue life, and fatigue life can be greatly increased with aging at 300℃.
