High-Temperature Structural Transformations and Properties of Single Crystals of Intermetallic Alloy VKNA-25-VI upon Microalloying with Rare-Earth Elements

The effect of rare earth elements (lanthanum and scandium) on the endurance of alloy VKNA-25-VI in long-term strength tests at 1100°C and on its resistance to high-temperature oxidation is determined. The microstructure of the alloy is studied before and after the tests.
