Abstract Superplastic structures have been developed in an as-cast ultrahigh carbon steel, containing 1.6% C, by heat treatment alone. The heat treatment involves quenching from high temperature (1150° C) and then repeated cycling across the A1 transformation temperature (727° C). This changes the coarse, as-cast structure to an ultrafine ferrite structure containing fine spheroidized cementite particles. An optimum structure is found after about 10 cycles and strain rate sensitivities of about 0.45 and elongations to failure of over 300% have been achieved.
