| Abstract: | Duplex thermochemical processing of 13Cr4Mo4Ni4VA steel was carried out,which involves carburizing(followed by hardening and tempering) and then nitriding.Optical microscope(OM),Scanning electron microscope(SEM),X-ray diffraction,electron probe micro-analyzer(EPMA),and microhardness tester were used to investigate the evolution of microstructures and properties during the duplex thermochemical processing of 13Cr4Mo4Ni4VA steel.The results indicate that the carbon and nitrogen introduced into 13Cr4Mo4Ni4VA s... |
