Hot workability of waste particles reinforced Al-7Si-0.3Mg alloy hybrid composites characterized using processing maps

Abstract Waste particles are the huge environmental problem facing today. The aim of present study is utilization of waste materials into raw materials which will reduce the material cost and favorable for industrial sectors. Aluminium with organic and inorganic particles is prepared by using double stir-casting process. The hot deformation behaviour and workability of Al alloy hybrid composites are investigated using hot compression tests at three different temperature and strain rates. The processing maps were constructed using MATLAB. The A356/5% (RHA-Fly ash) hybrid composite achieved more efficiency compare to base alloy. The stability domains are increased by addition of waste particles.
