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 DEG C. to 1100 DEG C., heating to 1200 DEG C., heating to a temperature of 1200 DEG C.<T</=1300 DEG C. at a heat-up rate of less than or equal to 1 DEG C./min, and a multistage homogenization and dissolution process at a temperature of 1300 DEG C.</=T</=1315 DEG C.
