摘要
Special features of structure and phase formation in deposited metal based on alloyed Ni3 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.
