OSTI ID:6002974
The effects of austenitizing and tempering heat treatments on carbide precipitation in the alloy HT-9 have been investigated and documented. The study indicated that for specimens tempered at 650, 700, and 750/sup 0/C the amount of carbide precipitation was independent of the austenitizing temperature. However, for specimens tempered at 800/sup 0/C, the carbide precipitation varied as a function of austenitizing temperature. The maximum carbide precipitation for an 800/sup 0/C temper treatment occurred at 1175/sup 0/C austenitizing temperature. Carbide size at constant tempering temperature varied as a function of austenitizing temperature for all temper treatments. Samples austenitized at 1100/sup 0/C and tempered at 650/sup 0/C showed an unusually high carbide size in relation to other samples tempered at 650/sup 0/C. Carbide size as a function of tempering temperature increased with increasing austenitizing temperature.
