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)...

| 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) AZ91 Mg alloy. The variations in tensile properties with respect to different castings are explained using the microstructural quantities; average size, area fraction, number density and clustering tendency (CT) of microporosity, massive continuous and discontinuous Mg17Al12 particles, and grain size. Evidence of different micro failure modes of the material are presented to explain the influence of different micro features on failure. The extend effects of shrinkage porosity and β(βm,βc and βd) particles on the deformation and failure of the material are discussed. |
