Structure, Mechanical Properties, and Fracture Behavior of a Fe-Cr-V Alloy Doped with Nitrogen by High-Temperature Gas-Phase Nitriding

“…VOLUME high-temperature nitriding method at T = 1173 K to 1473 K (900°C to 1200°C) is promising for improving the complex properties of the entire volume of the material in the case of thin-walled articles due to saturation of the material with nitrogen. [1][2][3] In contrast to the traditional surface nitriding, during high-temperature nitriding, the formation of a continuous layer of nitride on the surface is suppressed. [1,[4][5][6] In this case, stable nitrides of alloying elements arise in the form of disperse particles distributed in the matrix, which stabilize the structure at high temperatures and ensure the efficient hardening of material.…”

[7][8][9] It is also known that high mechanical properties stable for a long time at high temperatures and stresses can be obtained in steels by combining solid solution hardening with hardening by particles of second phase, [10,11] which is achieved at high-temperature nitriding.…”

Production of iron matrix composite reinforced by TiN particulate through nitriding by powder metallurgy

“…It can be a good potential reinforcing candidate. Petrova et al [6][7][8] studied the formation of TiN compound in austenitic steels and wrought nickel base alloys by the nitriding process. The service temperatures of austenitic steels increase by 100-150uC and those of wrought nickel base alloys increase by 200uC.…”
