Phase transformation of carbide in ultrahigh-carbon steel

An ultrahigh-carbon steel (UHCS) containing 2.035 wt.% carbon and 10 wt.% chromium was processed to obtain ultrafine spheroidized carbide, pearlite and ferrite structure, respectively. The microstructure of this steels were investigated by light microscopy. The Phase transformation and phase transition of carbide were discussed and investigated. The present results indicate that ultrahigh-carbon steels can be easily processed to achieve unique microstructures and properties
