摘要

The steel under consideration is a low-alloy (.18C, 2.8 Cr, .6 Mo, .3 V in wt-%) pressure vessel steel heat treated to a yield strength of about 600 Nmm to the minus 2nd power at room temperature. The temperature dependence of the yield stress can be characterized by an equation, and from this equation the temperature at which the fracture stress and general yield stress of a notched specimen coincide can be solved. The temperature calculated in this way and the experimentally measured temperature correspond to each other with an accuracy of 10 K.
