摘要：In this study, tensile test and Charpy impact test of domestic A508-III steel are carried out in the ductile-brittle transition range, in which obtained the mechanical properties and temperature dependence of Charpy impact energy. Fracture toughness test temperature is determined through the correlation with characteristic temperature, at which Charpy impact energy is 28 J or 41 J. The Master Curve of 12.7 mm SE(B) is respectively from the single-temperature and multi-temperature method, and measured T0 was valid. The result shows that the reference temperature T0 derived from two methodsis basically consistent. And the reference temperature T0 of domestic A508-III steel is about -63°C.
