| Abstract: | Ultrahigh-carbon steels (UHCSs) with the microstructure of ultrafine spheroidized carbides distributed in ultrafine ferrite grains is a new family of materials which has been developed in recent years abroad-These steelspossess unique properties that are unavailable in other materials,which means that they have important potential structural applications in the latter ones. In this article, chemical composition design, producing techniques and microstructural and superplastic properties are reviewed,and prospect of ultrafine grained ultrahigh-carbon steels is discussed. |
| Keywords: | ultrahigh-carbon steels ultrafine grains chemical composition producing techniques microstructures properties superplastic |
