Abstract

Technological capabilities for casting of long turbine blades with an axially oriented single-crystal structure 〈001〉 produced from low-density superalloy are explored. The principles of designing starting cavities for single-crystal casting of blades are considered. The produced structures of model blocks for long blades with selected parameters of superalloy casting at the UVNK-type production unit for directional solidification equipped with an automated control system for the casting process (G = 60–80°/cm) make it possible to fabricate the blades with single-crystal structure throughout the height. The major physicomechanical properties of the alloy with crystallographic orientation (CGO) 〈001〉 are provided. The results of studying the characteristics of the single-crystal as-cast structures of long blades made of Ni-based superalloy are presented: the quantification of the microstructure, the data on the structure-phase characteristics of material in single-crystal blades after casting, and the data of electron-probe microanalysis.
