Abstract

Discusses issues related to the development of technological process of production of casting blades of gas turbine engines from an alloy based on Nb–Si composite. Optimized extrusion parameters and the properties of high-refractory ceramic members consisting of yttrium oxide. Made of ceramic shell molds and investigated their basic characteristics. Held die-casting blades high temperature alloy based on Nb–Si directional solidification. Studied the nature of the interaction of the melt with the material and shape of the rod. Conclusions about efficiency of the developed technologies for producing ceramic cores and forms on the basis of yttrium oxide in the casting of blades from alloy on the basis of Nb–Si composite. The work is executed within the implementation of the complex scientific direction 9.1. «High-temperature single-crystal superalloys, including natural composites» («The strategic directions of development of materials and technologies of their processing for the period
