ABSTRACT:
In section bars and shaped bodies made of nickel-base superalloys having a structure consisting of columnar grains, a complete recrystallization cannot be effected unless the heating-up rate is kept below a maximum heating-up rate T.sub.max, which depends on the ratio V of one or more of the metal carbide-forming elements hafnium, niobium, tantalum, titanium and zirconium to one or both of the metal carbide-forming elements tungsten and molybdenum.
