Abstract

The structure and properties of a castable intermetallic alloy of grade VKNA-4U-mono with single crystal structure at a temperature range of 20 – 1250°C is considered. The effect of long-term heating at 1200°C on the stability of mechanical characteristics of the alloy is studied. The advantages of the alloy and its technological and physical properties are described.
