对大截面C45R钢正火出现冲击功偏低进行分析,结果表明,正火组织出现粗晶、混晶和网状铁素体是冲击功偏低的主要原因。优化正火工艺可以有效改善组织,满足生产技术要求。

After the analysis for low impact energy of C 45 R steel with great section by normalizing ,it is found that main cause of low impact energy is normalizing structure with coarse -crystal ,mix-crystal and network ferrite .Opti-mizing normalizing process can improve the structure effectively ,and satisf...
