- Step E4 of thermal treatment for precipitation of phase g ' is carried out by one or more incomes which allow the reprecipitation of phase g' in the desired form.
- Stage E4 of thermal treatment for precipitation of phase g ′ can for example be carried out by a first tempering at a temperature between 800 ° C and 900 ° C, typically 850 ° C, which is followed by a second tempering at a temperature between 700 ° C and 800 ° C, typically 750 ° C.
