Ultrahigh carbon steels containing 1 to 2 mass% carbon exhibit superplasticity at temperatures below and above the A{sub 1} temperature when their microstructures are controlled to be a fine ferrite ({alpha}) grain structure with a uniform distribution of spheroidized cementite (Fe{sub 3}C, designated as {theta} in this paper) particles, i.e. an ({alpha} + {theta}) microduplex structure. The aim of the present study is to find heat treatment methods without any deformation by which a microduplex structure can be obtained. The effects of alloying elements and heat treatments on the formation of a microduplex structure in ultrahigh carbon steels have been investigated.
