説明
The formation of fine grain structure in steels by various severe plastic deformation processes, such as ball milling, equal channel angular process and accumulative roll bonding are distinctly demonstrated. In a new process to achievement grain refinement, the back-torsion working was devised. In present study, the S10C steel treated with its working has been produced using the conventional torsion apparatus, and subsequently the microstructure evolution and mechanical properties have been investigated. The shape restoration phenomenon, fine grained and hardening by back-torsion was confirmed. The deformed grain size as functions of rotational number, ±n and distance from centre, r is predicted and compared favorably with experimental measurements. The relationship between measured hardness and grain size known as Hall-Petch equation is clarified in a present steel with its working. Focusing on deformed dual phase steel including soft/hard (ferrite and pearlite) phases, profitable conditions to produce material balanced strength against ductility are discussed based on the results of microstructure observation and fracture mechanics analysis.
