稀土变质、多元微合金化处理的高锰钢淬火新工艺

A New Quench Technology of High Manganese Steel with RE Modificaltion and Multi-component Micro-Alloying

经稀土变质、多元微合金化处理的高锰钢，其铸态组织形态、大小、间距及分布状态均发生了很大的变化。与普通高锰钢相比，强韧性有了显著提高，热裂现象在很大程度上得以消除，抗磨性能大大增强。据此提出：应根据该材质铸件结构的特点及复杂程度，参考使用条件及对其性能的特殊要求，分别采用简单实用、经济合理的淬火新工艺。

For high mangamese steel REmodificaltion and multicomponent micro-alloying cause a great change in its cast structure size, interval and distribution. Compared with common manganese steel, it's strength and toughness was apparently enhanced. Heat crack was hindered or eliminated and anti-abrasive property was enhanced obviously. The paper points: According to all kinds of casting structure, complexity, work condition and specifik requirment of its properties, simple, practical, economic quenching should be ...
