Investigation of Microstructure and Mechanical Properties of Spray Atomized Al-5wt. % of Zn Alloy

Abstract

This paper describes the processing of an Al-5 wt.% Zn alloy using the spray atomization technique and investigates the resulting microstructural and mechanical properties of the alloy. The average grain size value is 163 m, hardness of the alloy is 27 MPa and the density was  2.13±0.0145 g/cc. This paper gives the information about the arrangement of grains in the alloy of spray deposits. Optical Microscope revealed the peripheral region of the alloy is having coarse, elongated and equiaxed grains are observed. The ultimate tensile strength of the spray formed material was 426 MPa.
