| Abstract: | Dehydrizing processes and mechanical properties of samples after gas nitriding were studied .The results show that different steels have different dehydrizing processes, hydrogen content on the surface layer and mechanical properties of test specimens are different by dehydrizing at different temperature. Dehydrizing processes of 4Cr14Ni14W2Mo steel,18Cr12Ni4WA steel and 38CrMoAlA steel are obtained. |
