◎ a=air; w=water; g=gas. ① When heat treatment forms part of further processing of the product. an attempt should be made to achieve the lower values of the range for solution annealing. lf hot working has been carried out at a temperature of at least 850 °C or if the product has been cold worked, the temperature used for subsequent solution annealing may be 20 °C less than the lower limit stipulated for solution annealing. ② Cooling should be sufficiently rapid. |
