摘要
测试了２０Ｃｒ２Ｎｉ４Ａ钢８２０℃碳氮共渗层中的碳氮马氏体低温回火时的硬度变化和工业纯铁经６８０℃氮碳共渗后渗层中的含氮马氏体回火过程中显微硬度的变化。
The hardness variation of carbon nitrogen martensite of carbonitriding layer of 20Cr2Ni4A steel carbonitrided at 820℃ in low temperature tempering is measured. And the microhardness variation of nitric martensite of the penetrated layer of commercial pure iron nitrogencarbonated at 680℃ in tempering is also measured.
