Research phase formation in Fe-Ni system by mechanical alloying

Metallurgy and materials technology. Mechanical engineering

Shown that mechanical activation iron powders and their alloys in air leads to a significant oxidation. To prevent oxidation, mechanical activation of Fe-Ni alloy was conducted in atmosphere of ammonia. It was found that mechanical activation Fe-Ni alloy in atmosphere ammonia leads to saturation with nitrogen, increasing mechanical activation time content γ-phase increases.
