Abstract
A NUMBER of zinc-based alloys containing equiaxed particles of various stable and insoluble hard second phases were prepared as part of an investigation into the high-temperature compression creep characteristics of dispersion-hardened materials1. It was found that the dispersed particles produced a substantial strengthening effect at temperatures above 0.60 of the absolute melting temperature of zinc. Room-temperature tensile tests were made in order to measure the expected loss in ductility of zinc caused by the hard particles. It was surprising to find, therefore, that most of the dispersed particles reduced the strength and increased the ductility of zinc. These results are briefly reviewed here.
