GB GH 4706 Heat Treatments

Solution treatment: At 950°C - 1010°C, select a temperature within this range ± 10°C; the holding time should be not less than 1 hour. Cool slowly, in air, or by a faster method.
Aging: 730°C ± 10°C, aging time 8 - 18 hours, furnace cooling rate of 55°C/h ± 10°C/h to 620°C ± 10°C, then aging for 8 - 36 hours, and air cool.
