Abstract

Superplastic deformation in metal matrix composites of titanium alloys was investigated during thermal cycling. The effect of whisker volume fraction on transformation superplasticity of the specimen was studied. The observed trends were explained in terms of load transfer from the matrix to whiskers during deformation. Experimental results revealed a linear relationship between the superplastic strain increment after each thermal cycle, and the applied tensile stress. There was a decrease in the deformation rate and achievable superplastic elongation with an increase in the volume fraction of reinforcement.
