Abstract
Fine grained copper-based or nickel-based memory alloys having a matrix of .beta.-high temperature phase with metal oxide particles dispersed in the matrix which act to retard grain growth have improved mechanical characteristics such as elongation, toughness and workability, compared to cast and worked alloys. These alloys are produced by powder metallurgy.
