摘要
采用粉末冶金与原位合成相结合的技术,以铁粉、钛粉、石墨和锰铁粉等为原料,制备了碳化钛颗粒增强高锰钢复合材料。采用扫描电镜(SEM)对复合材料的微观组织进行分析。结果表明:原位合成的碳化钛颗粒在基体中均匀分布;碳化钛颗粒与基体的界面干净,界面处存在元素的浓度梯度。
Using iron powder, titanium powder, graphite and ferromanganese powder as raw materials, TiC reinforced high manganese steel composite was produced by powder metallurgy and in-situ synthesis technique. The microstructure of the composite was studied by SEM. The results show that the uniform distribution of the TiC reinforcements on the iron matrix is successfully obtained. The interface between TiC particles and iron matrix is clean and there is element concentration gradient in the interface.
