Upon nitriding of iron‐based alloys, development of misfitting coherent nitride precipitates in a ferrite matrix induces an overall expansion of the ferrite lattice. This lattice expansion was quan‐ titatively determined by X‐ray diffraction from the change of the lattice parameter of ferrite of homogenously nitrided Fe‐Cr and Fe‐V alloys. Adopting the experimentally verified (by X‐ra...

Herein, rhombohedral self-doped KNbO3 (S-KN) nanorods were fabricated via a one pot, solvothermal method without using any surfactant. The presence of Nb(4+) in S-KN greatly narrows its band gap and thus extends its photoresponse from UV to the visible light region. Moreover, S-KN/Nb4N5 nanorod heterostructures were obtained by nitriding S-KN nanorods for different times, which exhibited signif...

The influence of regime (temperature, composition gas mixture and its pressure) energy characteristics (voltage, current density, specific discharge power) at hydrogen-free-nitriding in a glow (HFNGD) on the structure, phase nitrided layers is investigated. It shown that due to combination parameters HFNGD it possible achieve physical chemical indicators set by operating conditions. traditional...

Abstract A Fe–3wt pctSi alloy was gas nitrided to study the effect of Si on Fe nitride formation. Both ε -Fe 3 N 1+ x and γ ′-Fe 4 were observed at nitriding conditions only allowing form single-phase ′ layers in pure α -Fe. During short times, simultaneously grow contact with Si-supersaturated -Fe(Si). nitrides almost invariably exhibit crystallographic orientation relationships -Fe, which are...
