摘要：

A new process to obtain ultrafine grained bulk steel was developed. Plain low-carbon steel sheet with martensite starting microstructure was simply cold-rolled by 50% and annealed. The specimens annealed at intermediate temperatures such as 773 K revealed the multiphased nano-structure and showed superior mechanical properties. (C) 2002 Acta Materialia Inc.
