摘要:
运用原位合成反应工艺制备了TiC颗粒增强Fe3Al基复合材料.显微分析研究表明,在Fe3Al中引入TiC颗粒,可以有效地细化材料的显微组织,从而改善材料的热变形加工工艺性能.TiC增强体不仅本身具有很高的热稳定性,而且也大幅度提高了复合材料的热稳定性.对复合材料进行的一系列性能测试结果显示,在Fe3Al中加入TiC颗粒后,材料的室温和高温强度和抗蠕变性能得到显著提高,但是在一定程度上降低了材料的室温塑性.
Abstract:
Fe3Al matrix composites reinforced by TiC particulate were produced by using in-situ reaction technique. Microstructure observations show that the addition of TiC particles can refine the microstructure and is beneficial to the deformation processing. In the Fe3Al matrix the TiC particles have very high thermal stability and they can increase the thermal stability of the composite greatly. A series of test on the property of the composite shows that the addition of TiC particles to the Fe3Al matrix results in remarkable increase of strength and creep resistance at both room and high temperatures and a certain decrease of ductility at room temperature.
