The high-temperatureductility deteriorates and intra-granular strength increases with an increases of dynamic precipitation of carbide.
结果表明:晶内强度随碳化物动态析出量的增加而上升,高温塑性随之而降低。
2
At room temperature and hightemperature the tensile strength of the forging decreases firstly and then increases while the ductility changes on the contrary.
室温和高温拉伸强度随锻造火次的增加呈现先减少后增加的趋势,塑性则先增加后减小。
3
After magnesium treatment the ductility of steel was increased at hightemperature.
