THE MICROSTRUCTURE and HARDNESS ANALYSIS of WELDED ALUMINUM MATRIX MATERIAL REINFORCED WITH SiC USING DIFFERENT WELDING CURRENTS ABSTRACT The welding of metal matrix material reinforced with ceramic particles has some problems such as formation of oxide layer, occurring segregation on welding area, and reacting of ceramic particles with welding bath. The expected mechanical properties cannot be obtained because of these problems.In this study, the weldability of aluminum 2014 alloy reinforced with SiC particles was investigated.MIG welding process was used via using AlSi5 alloy wire at different welding currents.Welding current effects on the microstructure and hardness distribution were examined. Key Words: Metal matrix composite, microstructure, MIG, SiC, Aluminum
