Abstract:

Recovery in the aging of alloy Kh2ON80T, indicates that during its heating at a higher temperature the change in properties, chacteristic for this elevated temperature of aging after hardening, does not occur at once. The minimum in the hardness of the alloy, attainable during recovery, is lower and the heating time for recovery is less at a higher tempeature. With reatment for recovery of the alloy aged after quenching in water, the srengthening obtained during the initial aging is not completely eliminated. With treatment for recovery of the alloy aged after slow cooling from the temperature of diffusion annealing, the strengthening obtained by the alloy during initial aging is completely eliminated. Repeated aging of the alloy after treatment for recovery occus in the same manner as initial aging strengthening acquired is determined by the temperature of the repeated aging and prior heat treatment.
