OSTI ID:6138550
Based on the data acquired in this study, the effects of austenitizing and tempering heat treatments on the impact energy of HT-9 can not be completely known or understood. The Charpy-impact transition temperature (ITT) was depressed 38/sup 0/C by decreasing the austenitizing temperature from 1000/sup 0/C to 900/sup 0/C. However a decrease from 1100/sup 0/C to 1050/sup 0/C produces an increase in the ITT of 40/sup 0/C. The lowest ITT was found to occur at -10/sup 0/C. This condition was produced by an austenitization at 1100/sup 0/C. An inverse relationship between grain size and ITT was found to exist in the range of grain sizes from 4 to 8. At a grain size of 3, the ITT was found to be -10/sup 0/C and the inverse relationship is invalid. Further research is needed in the range of larger grain sizes.
