Abstract:

Superplastic behaviour has been examined in the Pb-Sn-Zn and Pb-Sn-Cd ternary eutectic alloys. Both alloys exhibited log ?_t/log ?_t and m/log ?_t relations similar to those of comparative binary eutectic alloys. Activation-energy values and metallographic observations indicated that the deformation mechanism was consistent with grain-boundary sliding. It was also concluded that the multiplicity of types of interphase boundary does not play a significant part in determining superplastic behaviour.
