Hicho, R. Fields] Heat treating experiments, where the austenitizing temperature was varied, were conducted on HSLA-80 steel in order to determine if the impact properties, particularly at −17.8° C and −84° C, could be increased to those of HSLA-100. The impact properties were found to decrease as the austenitizing temperature increased and were dependant upon plate thickness. Selected heat treatments conducted on the 19 mm, 32 mm, and 51 mm thick plates produced acceptable impact results. The trend observed in the 19 and 32 mm thick plates was not as pronounced in the 51 mm thick plate due to its inability to attain a sufficient cooling rate. Impact tests were also conducted on specimens taken from the 19 mm thick plate and given a double austenitizing treatment. The effects of E-copper and niobium carbide precipitates on the impact strength are discussed. Springer-Verlag New York Inc., 1990 Hicho G.
