Production characterization and friction stir welding of aa6061zrb2 in situ composites

Abstract

Conventional monolithic alloys fall short to meet the ever increasing demand to enhance product capabilities Ceramic particulate reinforced metal matrix composites MMCs have gained the attention of the present era MMCs exhibit superior properties over conventional monolithic alloys such as high wear resistance low thermal expansion high strengthweight ratio etc MMCs find application in aircraft structures space shuttles military and shipbuilding MMCs research has to go a long way to attain maturity for its application to all fields of engineering Intensive research is required to fabricate MMCs economically SiC and Al2O3 were predominantly used as reinforcements in the early decades of MMCs development newline
