在本研究中，含有氮化鈦顆粒的鋁基體是通過內在反應及直接添加TiN製造，在內在反應中氮氣與液體熔體中的鈦反應形成TiN。 在Al合金基體中內在反應形成TiN顆粒後，拉伸強度與屈服強度增加高達20％，而硬度增加高達27％。隨著TiN顆粒的內在反應形成，以及直接添加TiN顆粒，耐磨損性和耐滑動磨損性增加。在疲勞實驗中，利用內在反應法TiN顆粒增強之鋁合金複合材料與直接添加TiN顆粒之鋁合金複合材料在抗拉強度與抗疲勞強度都有顯著的增加。其中內在反應法TiN顆粒鋁合金複合材料的抗拉強度與抗疲勞強度又比直接添加TiN顆粒鋁合金複合材料要好，其原因為內在反應法TiN顆粒鋁合金複合材料中的TiN顆粒比直接添加TiN顆粒鋁合金複合材料中的TiN顆粒細小並與鋁基體結合牢固，TiN顆粒與鋁基體間沒有裂紋的存在，這使得內在反應法TiN顆粒鋁合金複合材料擁有較高的抗疲勞強度，而且內在反應法TiN顆粒鋁合金複合材料之耐磨耗性較直接添加TiN顆粒鋁合金複合材料高。

In this paper, an aluminum matrix containing titanium nitride particles was fabricated by an in situ process in which nitrogen gas reacts with titanium in the liquid melt to form TiN. The tensile and yield strength increased by up to 20% after the formation of TiN particles in the Al alloy matrix, whilst the hardness increased by up to 27%. The abrasive and sliding-wear resistance increased with the in situ process and direct addition of the TiN particles. TiN particles of aluminum alloy composite material with in situ process and the direct addition of TiN aluminum alloy composite material have significantly increased tensile strength and fatigue resistance. Among them, TiN aluminum alloy composite material in situ process has better tensile strength and fatigue resistance than the direct addition of TiN aluminum alloy composite material. The reason is that TiN particles with aluminum alloy composite material in situ process is smaller than the commercial TiN powder, and integrate with aluminum matrix strongly. Moreover, there is no flaw between TiN particles and aluminum matrix. It makes TiN particles of aluminum alloy composite material with in situ process have higher fatigue resistance,and the wearability of TiN particles of aluminum alloy composite material with in situ process is superior to the direct addition of TiN particles aluminum alloy composite material.
