摘要：

The dissolution behavior of cementite by heavy deformation in eutectoid steels with pearlitic and spheroidite structures was studied. To examine the thermal effect on the cementite dissolution, pulsed laser heating was also carried out. By ball drop deformation, the cementite dissolved and the matrix became nano-grained. After pulsed laser heating, re-austenitized region transformed to fresh martensite during quenching. The boundary between the re-austenitized region and matrix exhibited similar microstructure with that observed in specimens subjected to ball drop deformation. It was suggested that the dissolution of cementite by heavy deformation at high strain rate were probably due to thermal effect, that is, re-austenitization. (C) 2006 Elsevier B.V.
