In a heat treatment process for material bodies made of nickel base superalloys, in particular for monocrystals made of nickel base superalloys, the heat treatment of the material body comprises the following steps: annealing at 850.degree.C to 1100.degree.C, heating to 1200.degree.C, heating to a temperature of 1200.degree.C < T ~ 1300.degree.C at a heat-up rate of less than or equal to 1.degree.C/min, and a multistage homogenization and dissolution process at a temperature of 1300.degree.C ~ T ~ 1315.degree.C.
