Room temperature tensile tests were performed on zinc alloys containing submicron particles of Zn0, alpha A1203, carbon black and tungsten. Dispersion softening and substantial improvements in ductility as compared to pure zinc were observed when spheroidal particles were used. Strain softening was also encountered. The results are briefly explained on the basis of the fine and duplex slip which was observed in the composites. Stress field heterogeneity and thermal expansion effects were also considered. Author
