Superplastic characteristic of Mn–Si–Cr alloyed ultrahigh carbon steel realized through a novel process
A novel process based on simple heat treatment was developed in order to explore the superplastic characteristic of Mn–Si–Cr alloyed ultrahigh carbon steel. After austenitizing at A 1 − A cm and slow cooling, a microstructure with superplastic “potential” was obtained. The microstructure with superp...
