Present work focusses on the fabrication of Al-10% SiC-4% Kaoline HMMC by using conventional sintering, Microwave- assisted sintering (MAS) and Spark Plasma Sintering (SPS) techniques. Tensile, Compression and hardness tests were performed as per ASTM standards to study the effect of sintering mechanisms on the fabricated HMMC specimens. Results reveal that an enhancement of 13.3% in U.T.S and 11.7% Compression strength was observed in the Spark Plasma Sintered HMMC when compared to conventional sintered composite specimens because of lesser sintering temperature, time and the absence of intermetallic compounds in the Spark Plasma Sintering process. The formation of the Al₂Cu intermetallic compound was identified in the XRD pattern of conventionally sintered Al-10% SiC-4% Kaoline HMMC sample due to the high sintering time and temperature which leads to inadequate mechanical properties. The fractured surface of tensile specimens reveals the presence of cleavages on the conventionally sintered HMMC which confirms the brittle fracture, and the existence of dimples on the Microwave sintered and Spark Plasma Sintered samples which signify that the ductile mode of failure in HMMC samples. Out of the three sintering techniques, Spark Plasma Sintering exhibits superior mechanical properties and lesser porosity levels.

目前的工作重点是通过使用传统烧结、微波辅助烧结 (MAS) 和火花等离子体烧结 (SPS) 技术制造 Al-10% SiC-4% Kaoline HMMC。根据 ASTM 标准进行拉伸、压缩和硬度测试，以研究烧结机制对制造的 HMMC 试样的影响。结果表明，与传统烧结复合材料试样相比，火花等离子体烧结 HMMC 的 UTS 提高了 13.3%，压缩强度提高了 11.7%，这是因为在火花等离子体烧结过程中，烧结温度、时间较短，并且不存在金属间化合物。Al ₂的形成由于高烧结时间和温度导致机械性能不足，在常规烧结的 Al-10% SiC-4% Kaoline HMMC 样品的 XRD 图中发现了铜金属间化合物。拉伸试样的断裂表面显示传统烧结 HMMC 上存在解理，证实了脆性断裂，微波烧结和火花等离子体烧结样品上存在凹坑，这表明 HMMC 样品中存在延性失效模式。在三种烧结技术中，火花等离子烧结表现出优异的机械性能和较低的孔隙率水平。
