Abstract

Recent achievements in engineering include the development and production of hybrid aluminium metal matrix composites (AMMCs), which are widely employed in all automotive applications due to their significant weight reduction and better strength compared to the base metal used in various manufacturing processes. The present work used burnt sugarcane bagasse powder (SCBP) as the filler material in aluminum–alumina composite. This filler material is inexpensive, low in density, accessible and widely available, renewable and ecologically innocuous. The fabrication of various AMMCs has been implemented using SCBP and alumina at different weight percentage ratios by powder metallurgy process. The validity of elemental composition is tested using energy-dispersive X-ray analysis, X-ray fluorescence, X-ray diffraction and CHNS studies. The specimens are made using an Instron machine at a pressure of 474 MPa and sintered for various lengths of time and temperatures. All specimens were checked for microhardness, uniaxial compression and fractography using the FMV1-MC-AT model, the Instron 8801 MT model, and the JEOL JSM-7001F model, respectively. The outcomes were compared with the base composite. At 600°C and for 2.5 h with 3 wt% burned SCBP, it was observed that relative density, microhardness and ultimate compression strength improved by 1.98, 28.18 and 24.27%, respectively.

通过粉末冶金对甘蔗基混合铝金属基复合材料的实验分析

最近在工程领域取得的成就包括混合铝金属基复合材料（AMMC）的开发和生产，由于在各种生产工艺中使用的铝金属基复合材料与基体金属相比，重量明显减轻，强度更高，因此被广泛应用于所有汽车领域。本研究使用烧甘蔗渣粉（SCBP）作为铝-氧化铝复合材料的填充材料。这种填料价格低廉、密度小、易于获得、来源广泛、可再生且对生态无害。通过粉末冶金工艺，使用不同重量百分比比的 SCBP 和氧化铝制造了各种 AMMC。使用能量色散 X 射线分析、X 射线荧光、X 射线衍射和 CHNS 研究测试了元素组成的有效性。试样使用 Instron 机器在 474 兆帕的压力下制作，并经过不同时间长度和温度的烧结。使用 FMV1-MC-AT 模型、Instron 8801 MT 模型和 JEOL JSM-7001F 模型分别对所有试样进行了显微硬度、单轴压缩和断口分析检测。结果与基础复合材料进行了比较。在 600°C 和 2.5 小时的时间内，在掺烧 3 wt% SCBP 的情况下，可以观察到相对密度、显微硬度和极限压缩强度分别提高了 1.98%、28.18% 和 24.27%。
