Abstract
Results of the aging studies in the temperature range of 1300-1600°F show that substantial hardness increase occurs for all temperatures within the first minute of aging. The initial increase in hardness at 1500°F is associated with clustering and this clustering leads to the generation macrostresses. Precipitation of coherent γ' was found to follow the clustering stage and this precipitation was found to follow a "C-curve" time-temperature relationship. Although regions denuded of γ' have been reported in the vicinity of carbides after long aging periods, no evidence of such denudation was found in samples aged up to 30 minutes in the range of 1300-1600°F.
