Optimization of lm25 aluminium Metal matrix composite parameters Reinforced with fe3o4 using nonconventional Machining process

Abstract

In recent years aluminium metal matrix composites AMMCs newlinehave emerged as promising high class materials The surface roughness newlineand wear properties are the basic material parameters required in the design newlineand the optimization of composite structures and behaviours Metal matrix newlinecomposites are emerging as very promising materials especially in the newlinefields of aerospace electrical electronics and automotive for their various newlineapplications and technical demanding properties Iron oxide Fe3O4 is newlinereinforced in the aluminium matrix composites to increase their newlineconductivity and characteristic mechanical properties such as hardness and newlinetensile strength LM25 aluminium alloy metal matrix composites MMCs newlinereinforced with iron oxide Fe3O4 particles up to 3 6 and 9 was newlineproduced by stir casting newlineIn this research tensile strength hardness improved stiffness newlinereduced density weight improved high temperature properties controlled newlinethermal expansion coefficient thermal heat management enhanced and newlinetailored electrical performance improved abrasion and wear resistance newlinecontrol of mass especially in reciprocating applications and improved newlinedamping capabilities were the focus of the investigations newlineThese composites have been evaluated and tested experimentally newline newline
