Abstract
A preliminary study was carried out regarding the relation between hardness and brittleness in steels. The temperature dependence of Vickers hardness on the steels was studied over a range from −196°C to 100°C. It was found that the logarithmic hardness versus the reciprocal of absolute temperature can be described by several linear stages. If the intersection of the two lowest temperature stages is defined as a hardness ductile-brittle transition temperature, the increase in the transition temperature during irradiation was approximately consistent with data obtained with the Charpy impact test. By obtaining the temperature dependence of hardness one should be able to detect easily embrittlement in steel.
