| Abstract: | 9.75% vanadium containing cold-work tool steel was successfully produced domestically by hot isostatic pressing of nitrogen atomized powder particles.The microstructure and mechanical properties were examined using scanning electron microscope(SEM) with energy dispersive X-ray diffraction(EDX).The phases and crystal structure of the specimens were identified by X-ray diffraction(XRD) and transmission electron microscope(TEM).It is found that the annealed sample consists of ferrite,MC carbide and M7C3 carbid... |
