采用ＸＤ法与搅拌铸造技术相结合的工艺制备了ＴｉＣｐ／ＺＡ４３复合材料，其中ＴｉＣ粒子的尺寸为０．５～１．５μｍ，在基体中分布均匀。对ＴｉＣｐ／ＺＡ４３复合材料室温至２５０℃温度范围的力学性能进行了测试，获得了该复合材料的应力－应变曲线及力学性能与温度的关系，并对其高温拉伸断口进行了分析。结果表明：ＴｉＣ粒子提高了材料的强度，尤其是显著提高了高温强度；ＴｉＣｐ／ＺＡ４３复合材料的断裂方式与拉伸温度有关，在２５０℃时呈现塑性断裂
TiCp / ZA43 composites were prepared by a combination of XD method and stirring casting technique. The size of TiC particles was 0.5-1.5μm, which was uniformly distributed in the matrix. The mechanical properties of TiCp / ZA43 composites were tested at room temperature to 250 ℃. The relationship between stress-strain curve and mechanical properties of the TiCp / ZA43 composites was obtained. The tensile fracture at high temperature was also analyzed. The results show that the TiC particles increase the strength of the material, especially the high temperature strength. The fracture mode of TiCp / ZA43 composites is related to the stretching temperature, which shows plastic rupture at 250 ℃
