Abstract
Metal matrix composites are considered as advanced materials in the field of automotive, marine and several industrial applications. In the present work investigations have been made on effect of nano B4C particulates addition on the tensile behavior of Al2219 alloy. Nano B4C particulates of 500nm were used as the reinforcements in the Al alloy matrix. Nano composites were synthesized by using liquid melt method in steps of 2 and 4 wt. % in the Al2219 alloy. Samples were tested for micro structural characterization by using scanning electron microscope and energy dispersive spectroscope. Tensile properties like ultimate tensile strength (UTS), yield strength (YS) and percentage elongation were evaluated as per ASTM standards. Scanning electron micro photographs revealed the uniform distribution of Nano B4C particulates in the Al2219 alloy and confirmed by EDS analysis. Further, ultimate tensile and yield strength of base matrix Al2219 alloy was enhanced with the addition of Nano B4C reinforcement. There was slight reduction in ductility of composites.
