渗碳钢齿轮中的残余奥氏体美通用汽车公司完成的几项试验表明，ＡＩＳＩ８６２０钢和４６２０钢含２０％一３０％残余奥氏体、３３１０钢内残余奥氏体含量达４０％时，可以明显的提高拉伸弯曲性能。在Ｆｅ一５Ｃｒ１．１２Ｃ钢中，当马氏体的百分含量超过７０％时，产生显...
Several tests performed by GM Austenite in carburized steel gear show that when AISI 8620 steel and 4620 steel contain 20% to 30% retained austenite and the residual austenite content in the 3310 steel is 40% Can significantly improve the tensile bending performance. In Fe a 5Cr1.12C steel, when the percentage of martensite over 70%, resulting in significant ...
