Purpose: Research and Development Laboratory for Aerospace Materials in Rzeszow University of Technology is the place where production of single crystal nickel base superalloys has been proved technically feasible. This paper presents the method of manufacturing the single crystal superalloys turbine blades and the prospective developments of the enterprise. Design/methodology/approach: Turbine blades were produced in the vacuum induction melting furnace ALD for investment casting of equiaxed, directionally solidified and single crystal materials. The CMSX-6 nickel based superalloy is used for production of turbine blades. Findings: The ceramic moulds production process was formulated. All main parameters of single crystal production was accordanted. Research limitations/implications: EBSD analysis clearly revealed that the casted turbine blades are single crystals and possessed [001] crystal orientation. Originality/value: The paper gives a general review of the technology of production single crystals turbine blades.
