Present industries show an increasing demand in low-cost reinforcement and light weight composites. As compared to unreinforced alloys, metal matrix composites (MMCs) have possessed better properties including good thermal conductivity, wear resistance and high strength. The inexpensive low-density reinforcement of several discontinuous dispersions is available in huge quantities of agricultural waste is activated carbon (AC). Hence, the composites with activated carbon as reinforcement in Al-Si alloys (AMMC) are likely to find wide spread applications in aerospace, marine and automobile sectors. The current examination has been cantered at the usage of titanium carbide (TiC) and activated carbon (coconut shell ash powder) in micro form, with the aid of dispersing it into aluminium silicon alloy (A413) to yield composites via stir casting method. Hybrid reinforcement of 1, 2 & 3% of TiC and 5, 10 & 15 % of activated carbon via weight %, specimens have been prepared by using liquid metallurgy route. Tests like wear behaviour, mechanical tests and microstructure studies are executed and analysed. From the investigation it has been revealed that with increase in the % reinforcements of TiC and activated carbon improving the mechanical properties of the composites such as hardness and tensile strength. The microstructure pictures have revealed the distribution of TiC and AC reinforcement uniformly in the Al-Si matrix.

碳化钛和活性炭颗粒对A413金属基复合材料磨损，力学性能和微观结构的影响

当前的行业显示出对低成本增强和轻质复合材料的需求不断增长。与未增强合金相比，金属基复合材料（MMC）具有更好的性能，包括良好的导热性，耐磨性和高强度。几种不连续分散体的廉价低密度增强材料可用于大量农业废料，即活性炭（AC）。因此，在铝硅合金（AMMC）中以活性炭为增强材料的复合材料很可能在航空航天，船舶和汽车领域得到广泛应用。目前的检验因使用微粉状的碳化钛（TiC）和活性炭（椰子壳灰粉）而分散，并借助于将其分散到铝硅合金（A413）中来生产复合材料 通过 搅拌铸造法。的1，2，的TiC的3％和5％，10＆活性炭的15％的混合增强件 经由 重量％，试样已制备通过使用液体冶金路线。执行并分析诸如磨损行为，机械测试和微观结构研究之类的测试。从研究中可以看出，随着TiC和活性炭增强百分比的增加，复合材料的机械性能（如硬度和拉伸强度）得到改善。显微组织图片揭示了TiC和AC增强物在Al-Si基体中的分布均匀。
