| Abstract: | The effect of high temperature quenching followed by tempering on microscopic structures and mechanical properties of 3Cr2W8V steel has been studied by using X Ray Diffraction and Transmission Electron Microscope (TEM).The relationship of tempering transformation and punching toughness of the steel has been emphatically discussed.The experimental results indicate that the high temperature tempering embrittleness is related to the decomposition of retained austenite and the precipitation of carbide along the grain boundaries. |
