Special Features of Structure Formation in Deposited Metal Based on Alloyed Nickel Aluminide and its High-Temperature Properties

Special features of structure and phase formation in deposited metal based on alloyed Ni 3 Al nickel aluminide formed due to high-gradient crystallization under the conditions of the thermal cycle of arc surfacing are studied. The effect of microalloying with ultrafine WC carbides on the resistance...

Zusammenfassung:Special features of structure and phase formation in deposited metal based on alloyed Ni 3 Al nickel aluminide formed due to high-gradient crystallization under the conditions of the thermal cycle of arc surfacing are studied. The effect of microalloying with ultrafine WC carbides on the resistance to thermal fatigue and plastic straining at elevated temperatures (up to 1200°C) is considered.
