The impact toughness is the key to determine service life of high strength wear-resistant steel for lining boards large-scale semi-autogenous grinding mill (SAG). It difficult predict fracture failure when SAG running, which can cause damage equipment once it occurs. Therefore, novel was designed improve in this study. interestingly found that microstructure contained finer bainite/martensite, and rare retained austenite (around 2 vol.%), achieved trade-off between after optimal heat...
To avoid grain coarsening resulting from high-temperature carburizing, the effects of cyclic quenching and tempering on microstructure mechanical properties 18CrNiMo7-6 gear steel were investigated. Three groups samples compared, which went through 0/1/3 times quenching–tempering cycles after initial pseudo-carburizing. The variations in size, hardness, tensile strength, toughness systematically assessed using a series experimental techniques. results indicate that austenite size decreases...
