抄録

<p>As for ausforming of medium-carbon steel (Fe-0.56C-0.2Si-0.71Mn-0.017P-0.01 mass%S), it is investigated whether compressive stress during quenching changes the hardness of martensite. The result of hardness measurement indicates that the hardness of martensite is independent of compressive stress. In addition, whether some changes occur in the martensitic microstructure is investigated. There is no change in the size of martensite blocks and no change in the longitudinal direction of the martensite blocks. There is a slight tendency for specific variants to form preferentially in stressed test pieces. It is considered that the hardness does not change because the microstructure does not change significantly.</p>
