| 摘 要： | 采用重熔稀释法原位制备了不同质量分数的TiC颗粒增强的镁基复合材料,并对复合材料进行了力学性能测试。结果表明,原位合成的镁基复合材料的强度相比基体合金有了明显提高,塑性稍微降低。镁基复合材料强度的增加主要是因为位错强化、弥散强化和细晶强化协调作用的结果。

| Abstract: | Magnesium matrix composites reinforced with different weight fraction TiC particulates were synthesized using remelting and dilution technology. And mechanical properties of the composites were tested. The experimental results confirmed that the strength of the composites improved obviously compared to that of based magnesium alloy, while the ductibility of the composites decreased. The increase of strength on magnesium matrix composites is according to the effects of dislocation strengthen, dispersion strengthen and refine grain strengthen. |
