| 摘 要： | 在轧辊用铸造高速钢中添加K/Na-Si和K/Na-Mo进行变质处理,对试样分别进行高倍视频显微镜(HSVM)分析及力学性能测试。结果表明,高速钢经二次复合变质处理后,晶粒明显细化,组织更加均匀,共晶碳化物由网状分布变为块状和团球状,冲击韧性及耐磨性均明显提高。

| Abstract: | The dual-modification effect of K/Na-Si and K/Na-Mo on as-cast high-speed steel(HSS)used for rolls is researched and the effects on the structures and properties of as-cast HSS are also analyzed. The results show that the structures of HSS dual-modified by K/Na-Si and K/Na-Mo were obviously refined, the morphologies were more homogeneous, and the eutectic carbide networks were changed into spherical. After modification, the impact toughness was largely increased; all mechanical properties of inoculation HSS were close to that of forging HSS. |
