In this study, aluminium matrix (A6063) composites reinforced with titanium nitride and sugarcane bagasse ash were fabricated using liquid metallurgy technique. Reinforcements were added to a maximum of 10 wt% in aluminium alloy. The composites were then subjected to various mechanical properties study. Microscopic examinations were employed to analyse the distribution of reinforcement and phases in the composites. The tensile and impact test specimen after fracture was exposed to scanning electron microscopy to study the fracture mechanism. The tensile strength, hardness, yield strength and flexural strength of composites increased to a maximum of 29.7%, 31%, 34% and 7.7%, respectively. Ductility and impact strength decreased to a maximum of 47% and 11.5%, respectively. The presence of dimples, shearing, tearing microcracks, pull-out, stress concentration, hillock and particle fracture influenced the tensile and impact fracture mechanisms. Contribution of titanium nitride was higher in influencing the tensile strength, hardness, flexural strength and impact strength than that of bagasse ash.

在这项研究中，采用液态冶金技术制备了由氮化钛和甘蔗渣粉增强的铝基（A6063）复合材料。在铝合金中添加的补强最大为10 wt％。然后对复合材料进行各种机械性能研究。用显微镜检查来分析复合物中增强材料和相的分布。将断裂后的拉伸和冲击测试样品暴露于扫描电子显微镜以研究断裂机理。复合材料的拉伸强度，硬度，屈服强度和弯曲强度分别增加到最大值，分别为29.7％，31％，34％和7.7％。延展性和冲击强度分别下降至最大值47％和11.5％。酒窝，剪切，微裂纹撕裂，拉出，应力集中，小丘和颗粒断裂影响了拉伸和冲击断裂机理。氮化钛在影响抗张强度，硬度，弯曲强度和冲击强度方面的贡献高于蔗渣灰。
