Anotace
Development of casting technology for 10 types of castings with shape and dimensional complexity from highly reactive alloys. Increase the accuracy up to ± 0.4 mm. Increase of mechanical, creep and fatigue characteristics of investigated alloys. Development of technology for casting blades and segments with a cavity weighing up to 15 kg and increasing accuracy up to ± 0.5 mm. Research of the ceramic shell - melt interaction to reduce the reactivity of the metal. Limitation of the number of indications - surface defects - definition of permissible defects for a given type of casting on FPI. R&D work in the field of introduction of new types of materials for developed castings (EEQ 111, FSX 414 or B 1914). Research of fatigue and creep failure of investigated superalloys.
