Abstract
This article represents the stages of creation of new serial wear-proof and heat-resistant (at temperatures up to 1100 °C) cobalt–Nb-carbide cast eutectic alloys of the KhTN (ХТН) grade at the G.V. Kurdyumov Institute for Metal Physics of the N.A.S. of Ukraine, comparing them by their main properties, and use in aircraft engine engineering.

Keywords: cast eutectic alloys, cobalt, carbide, wear proofness, heat resistance, gas-turbine engines.
