Experimental Investigations On The Mechanical Properties Of A Disc Fabricated From Aa5052 Wastes Through Friction Stir Consolidation Process

Abstract

Friction Stir Consolidation (Fsc) Is A Recently Developed Metal Working Technology Which Involves A Solid-Phase Manufacturing Process That Consolidates Metal Powder, Chips Or Scraps Into Solid Blocks Via Severe Plastic Deformation And Solid State Welding. It Has The Capability To Be A More Economical And ?�?Green?�? Process To Recycle Metal Waste. The Objective Of This Research Was To Experimentally Investigate And Optimize The Process Parameters Of Friction Stir Consolidated Solid Disc Fabricated From Aa5052 Wastes And Finding Enhanced Mechanical Properties Namely Compression Strength And Hardness. In This Research, Solid Discs Were Produced From Aa5052 Aluminum Alloy Machining Wastes Through Friction Stir Consolidation Process. Furthermore, Design Of Experiment Was Conducted To Quantify And Optimize The Effect Of Die Rotational Speed, Aspect Ratio And Processing Time On Compression Strength And Hardness. Likewise Experiments Were Conducted By Taking Three Factors And Three Levels Namely: Speed (315 Rpm, 400 Rpm And 500 Rpm), Aspect Ratio (25.4/7, 25.4/5 And 25.4/3) And Time (30s, 45s And 60s) Then Compression Strength And Hardness Were Determined And Optimized. Minitab 2017 Software Was Used To Identify The Optimum Input Factors With Their Corresponding Levels. L9 Orthogonal Array Was Used And For Each Set Up Three Trials Were Taken To Reduce Variability Occurred Due To Noise Factors. Results Show That For Both Compression Strength And Hardness, The Optimum Processing Condition Is: A Process With Speed,
