Microstructure and Properties of TiC/Fe Matrix Composite Produced In-situ
摘 要
以铬铁粉、钼铁粉、钛粉、铁粉和炭黑为原料,原位反应合成了TiC/Fe基复合材料,并用扫描电镜、X射线衍射仪等方法对所制备的试样进行了组织结构分析.结果表明:未加钒时合成的复合材料主要相组成为TiC和α-Fe,硬质相TiC颗粒细小(≤2.3 μm);当加入一定量的钒后,复合材料主要相组成为(Ti,V)C和α-Fe,其组织更加致密,其抗弯强度升高;硬质相(Ti,V)C的面间距比硬质相TiC的面间距均有不同程度的减小;(Ti,V)C颗粒尺寸明显减小(≤1.6 μm),分布更均匀,颗粒形状趋于球形.
Abstract
TiC/Fe matrix composite was in situ synthesized by sintering compacts of mixed ferrochromium,ferromolybdenum,iron,titanium and carbon black powders.The microstructure of the composite was investigated using X-ray diffraction and scanning electron microscopy.The results show that the synthesized composite consisted of fine TiC particles and α-Fe as the binder phases when no vanadium was added.With the addition of vanadium,the composite consiste of (Ti,V)C particles and α-Fe,and the densification and bending strength of (Ti,V)C/Fe composite are higher than those of the TiC/Fe composite.Compared with TiC,the face spaces of (Ti,V)C were lower than those of TiC,(Ti,V)C particles exhibited finer size and more homogeneous distribution in the matrix,and their shape is round.
