TRANSITION FROM HALL-PETCH HARDENING TO SUPERPLASTIC BEHAVIOUR

Transition from Hall-Petch region to superplastic region has been established in the case of two commercially used superplastic alloys viz. Zn-Al eutectoid and Al-6Cu-0.5 Zr alloys. Tensile tests at various temperatures and for different grain sizes have been utilized for the experiment.
