Synthesis and Mechanical Characterization of Al Casting Produced by Slip Casting and Pressure Less Sintering

Abstract

The aluminum (Al) metallurgical parts have been used in various industrial applications including but not limited to structural, aerospace and automotive industries etc. owing to their excellent corrosion resistance, light weight, and good mechanical properties especially good specific strength [1-3]. In conventional ingot making, the properties of Al-alloys were improved by changing the composition of alloying elements, optimizing the processing techniques like heat treatments and mechanical treatments. There are various physical and mechanical properties which are not improved through ingot casting technique, and hence there is need to explore new processing techniques which can produce desire properties for complex shaped components. Metal casting is one of the important and widely used routes to shape Al metallurgical parts, however this process is health hazardous and not ecofriendly [4]. The powder metallurgy (P/M) can provide the possible solutions to the aforementioned issues associated with the production of Al metallurgical parts.
