Abstract

This work is aimed to conclude the effect of section thickness, position and long term annealing (LTA) on the microstructure and its influences on the tensile properties such as yield strength (YS), ultimate tensile strength (UTS), ductility and fracture strain (FS) of high pressure die cast (hpdc)...
