Effect of borides on the processes in metal deposited with 0Ni13Mo5Cr4VSiTiAl flux-cored wire at elevated temperatures

Abstract

The results of investigation of the service properties of maraging Fe–Ni–Mo–Cr–V–Si–Ti–Al with a composite structure, containing boride compounds, are described. The results show that the presence of the borides in the composition of the 0Ni13Mo5Cr4VSiTiAl flux-cored wire improves the shielding properties of the oxide film on the surface of the metal at high temperatures and results in high heat and scale resistance.
