✦ Synopsis

The wear resistance of Zn-Al alloys is determined in pin-on-ring wear tests, as a function of type of structure of the as-cast alloys. Three regions were observed; columnar, equiaxed and columnar-to-equiaxed grain transition. The results show that the equiaxed structure is the most resistant. In addition, the relation between wear rate and grain size depends on type of structure and it is more pronounced for the equiaxed structure. The effect is almost negligible for the columnar grain structure.

In this research microstructural studies have been made on cast specimens of AZ91 base alloys containing various amounts of Zn. As the amount of Zn addition increased up to 2%, any new Zn-containing phase did not appear while the Zn content in Mg 17 Al 12 phase continuously increased. A quasi-crysta
