Abstract

Stages of formation and development of single-crystal blade casting of heat resistant intermetallic alloys, composite alloys like VKLS, the creation of experimental industrial and industrial equipment for directed crystallization process and also development of blades cooling systems through creation of complex internal cavities are adduced. The problems connected with blades manufacture with the penetrating cooling system are considered. The forecast of getting blades with the penetrating cooling system without application of ceramic forms and cores, i.e. by additive technology is discussed.
