Cu-Ti alloys have great potential in the industry as a substitute for Cu-Be alloys which are expensive and pose health hazards, due to toxicity of Be during melting, casting and hot working operations. Cu-Ti alloys have properties comparable to those of Cu-Be alloys. Research is in progress for understanding the properties of Cu-Ti alloys. There exists a fair amount of understanding regarding precipitation mechanism in these alloys. However, little work has been done in the field of structure-property correlations in the Cu-Ti alloys. The purpose of the present investigation is to study the strain dependence of [sigma][sub o[var epsilon]] and k[sub [var epsilon]] for Cu-1.5wt% Ti alloy over a range of grain sizes (70--275 [mu]m) and to establish a grain size-flow stress relationship.
