Studies on structural characterization mechanical and wear behavior of 82cu4si14zn b4c nanocomposites fabricated through mechanical alloying

Abstract

Advanced engineering materials are highly in demand to have a combination of tailored properties in a single material nowadays. The nano grained processing of materials has paid much attention to fulfilling this requirement and refine the material properties which had attracted in many rese their superior properties such as high Strength to Weight Ratio (SWR), high stiffness, good wear resistance, high thermal, and electrical conductivity. Copper and its alloys have excellent properties such as high density, high strength, high thermal conductivity, good formability, and ease of machinability so which have perceived widespread applications in various sectors such as marine, aerospace, automobile, structural and electronic packaging. Silicon brass is a high ductility, and a lead-free alloy is selected as matrix material which is used in different machine elements such as bearings, gears, impellers, rocker arms, valve stems, brush holders, bearing races, and small boat propellers, etc. Lack of strength and high ductility limits its ability to withstand heavy load, toughness, temperature, and frictional conditions. This can be improved by strengthening the 82Cu4Si14Zn matrix and refine these properties by developing Fine Grained (FG) nanocomposites. Boron Carbide (B4C) is used as suitable reinforcement could uplift to enhance the matrix strength. By comparing other conventional methods, the advanced Powder Metallurgy (P/M) process Mechanical Alloying (MA) is an inevitable and effective way for uniform dispersion of secondary phase material within the matrix phase at the same time FG nanocomposite powders can be produced with a net or near-net shape products newline
