Abstract
The effects of alloying elements and heat treatments on the formation of microduplex structure in ultrahigh carbon steels were investigated. A fully pearlitic structure without coarse pro-eutectoid θ particles was obtained by the addition of 2 mass% Al. The microduplex structure consisted of fine grained α matrix with a grain size of 0.7 μm. The structure exhibited superplasticity, elongation of 490%, and a maximum flow stress of 35 MPa at 973 K and at an initial strain rate of 5×10-4/s.
