【Abstract】 The microstructure and properties of high chromium cast iron in different treatment states are studied by use of measurement technologies, such as XRD, OM, SEM and Hardness test. Experimental results show that materials with different morphology and structure have different performance and shorttime and middletemperature tempering can improve the materials’ service performance.更多还原
