Experimental study on atomic-scale strengthening mechanism of the ⅣB transition-metal nitrides

Insight into the Mechanisms of Nitride Films with Excellent Hardness and Lubricating Performance: A Review

“…Understanding and controlling the VEC in the film deposition process are crucial for achieving desired mechanical properties and performance in nitriding films. Han and coworkers [195] conducted an investigation into the strengthening mechanisms of transition-metal nitride films MeNx (where Me = Ti, Zr, Hf) across a wide range of compositions at the atomic scale. They suggested that the peak properties related to the composition are not the sole reason for grain refinement, preferred orientation, residual stress, or other strengthening mechanisms.…”

Refinement effect of TiC on ferrite by molecular statics/dynamics simulations and first-principles calculations

“…For a sphere embryo, K ¼ 2r . Thereby: (6) Gibbs-Thomson coefficient can be obtained by the following equation:…”

“…Nowadays, a lot of strengthening methods have been put forward, such as solid-solution strengthening, distortion strengthening, fine-grain strengthening and deposition strengthening [3][4][5][6]. Among them, the fine-grain strengthening method has attracted greatest attention for the improvement in strength and toughness of alloys simultaneously [7].…”

Effect of hafnium contaminant present in zirconium targets on sputter deposited ZrN thin films

“…During the last decades a great deal of advances has been made in the field of thin films, given their capacity to improve surface properties of components that present low lifespan or inferior performance when not coated [1][2][3]. In special, zirconium nitride (ZrN) thin films have attracted attention due to their high hardness and wear resistance [4,5], providing an increased performance to cutting tools and machining parts [6,7].…”
