| 摘 要： | 研究了０．１６Ｃ－１０Ｎｉ－１４Ｃｏ－１Ｃｒ－１Ｍｏ（１６ＮｉＣｏ）钢在５１０℃和０．２３℃－１２Ｎｉ－１４Ｃｏ－３Ｃｒ－１Ｍｏ（２３ＮｉＣｏ）钢在４８２℃回火的组织与性能。随回火时间的延长，强度、硬度的降低主要是由于Ｍ_２Ｃ的粗化及与基体共格性降低所致。Ｍ_２Ｃ的粗化速度２３ＮｉＣｏ钢要小于１６ＮｉＣｏ钢。

| Abstract: | The effect of tempering time on microstructure and mechanical properties of steel 0. 16C--10Ni14Co-ICr--IMc (16NiCo ) tempered at 510C and steel 0. 23C-12Ni--14Co-3Cr-IMc (23NiCo ) tempered at482C has been studied. The results show that with increasing tempering time the decrease of hardness andstrength of steel is attributed to coarseuing of M=C carbides and decreasing of its coherency with matrix ofsteel. The coarseeing rate of MZC carbides in steel 23NiCo is less then that in steel 16NiCo. |
