Transformational superplasticity associated with the eutectoid reaction in the Bi 2 O 3 ‐Sm 2 O 3 system was observed and characterized in hypoeutectoid and hypereutectoid compositions. Transformational strain varied linearly with applied stress and exhibited a stress‐axis intercept, or threshold stress, that is related to the proeutectoid microconstituent. Results are explained quantitatively using the analysis by Greenwood and Johnson and a creep mechanism.
