Resumo

This investigation is focused on the characterization of distinct environmental-friendly Al-p/Si-p composites. Differently from the traditional Al/Si composites, which are produced with Al-based alloy castings, the investigated composites are elaborated using Al and Si powder particles, sequentially compacted and sintered. The green and sintered densifications are determined, which are affected by both Si content and the applied compaction load. The preprogramming of the compaction pressure and sintering time induce to similar ultimate tensile strength (UTS) of an Al-Si casting alloy. The specific strength per relative manufacturing cost comparing with Al/SiC composites is also shown. Since the restriction legislations have banned hazardous materials, the proposed Al composites have an environmental-friendly aspect associated with a low manufacturing cost and recycling aspect.
