Abstract Scope |
In this presentation, the results of a study on two popular magnesium cast alloys, viz., the Mg-Al-Mn alloy (AM100) and the Mg-Zn-Cu alloy (ZC63) reinforced with saffil alumina short fiber using the squeeze infiltration technique will be highlighted. The unreinforced base alloys and the composites were investigated for their microstructure, mechanical properties and corrosion resistance. The results reveal the mechanical behavior of the Mg-MMCs to be dependent upon nature of the base matrix and microstructural phases present. Under salt spray corrosion condition, distribution of microstructural phases influences the corrosion resistance of the matrix. The behavior of composites also depends on fiber volume fraction. Composites of the two alloys reveal an improvement in strength when compared to the unreinforced counterpart, while under impact loading and corrosion, the composites had reduced properties. The inherent nature of alloy matrix on mechanical properties and corrosion behavior of magnesium metal matrix composites will be highlighted. |
