Iron-based ternary Fe–V–Si and binary Fe–Si alloy specimens were nitrided in a NH3/H2 gas mixture at 580°C (853K) with a nitriding potential of rN=0.1atm−1/2 until nitrogen saturation in the specimens was achieved. In contrast to previously investigated iron-based ternary Fe–Al–Cr and Fe–Ti–Cr alloy...
