Comparison of Enhanced Mechanical Properties and Texture of Pure Aluminium & Its Composite Processed by Powder Metallurgy and Equal Channel Angular Pressing

ABSTRACT

This research paper describes the synthesis of two solid billets processed by pure aluminium powder & zinc oxide powder, which was passed through parallel channel Pressing die to enhance mechanical properties and texture. Initially a die was designed for compaction, which consist of two die half and two plungers for top and bottom. Die parts were tightening together by using nut and bolts. After compaction, sintering was done using furnace. After that billets were passed first through parallel channel pressing die. Vickers Hardness, density, compressive strength and texture were evaluated before and after passing through parallel channel pressing die. Grain refinement and improvement in mechanical properties were observed by multiple passes of commercial billets of aluminium alloys. The research paper concludes the improvement in properties of billets prepared by PM (Powder Metallurgy) technique. Meanwhile there is lack of literature about PM techniques for aluminium alloys. In future PM will be a significant topic for research and samples made by (PM) Powder Metallurgy Technique will be easier to synthesize.
