“…The formation of TiCN was that the N position of TiN was partly replaced by C atoms to form a substitutional solid solution structure with FCC (face centered cubic) of δ‐NaCl, and the C atoms entered into the TiN lattices at a solid solution way, producing an elastic strain field. The C atoms were the center of the elastic strain field, when the dislocation movement appeared near the C atoms, and the larger resistance force was produced, increasing microhardness of the TiCN coatings . Because the lattice constant of TiN was slightly smaller than that of TiC coating, the lattice constant of TiCN coating was between TiN and TiC coatings.…”

A titanium carbonitride (TiCN) coating was deposited on YT14 cutting tool by using a CAIP (cathodic arc ion plating). The surfaceinterface morphologies, chemical compositions, and phases of TiCN coatings were observed by using a FESEM (field emission scanning electron microscopy), EDS (energy dispersive spectroscopy), XRD (X-ray diffraction), respectively, and the bonding energy, surface roughness, and bonding strength were characterized with an XPS (X-ray photoelectron spectroscopy), AFM (atomic force microscope), and scratch test, respectively. The results show that the phases of the TiCN coating are primarily composed of TiN, TiC, and amorphous C, of which the TiC and TiN increases the coating hardness, and the amorphous C atom improves friction and lubrication properties of the coating. The effect of CAIP on the topography of the TiCN coating is at nano-scale, the Ti and N atoms are enriched in the coating at the bonding interface, and the part of chemical elements are diffused in the gradual transformation layer. The bonding form of the TiCN coating interface is primarily composed of mechanical combination, accompanying with slight metallurgical combination, and the bonding strength is characterized with 60.85 N by scratch test.

Precipitation hardening stainless steels have attracted extensive interest due to their distinguished mechanical properties. However, it is necessary to further uncover the internal quantitative relationship from the traditional standpoint based on the statistical perspective. In this review, we summarize the latest research progress on the relationships among the composition, microstructure, and properties of precipitation hardened stainless steels. First, the influence of general chemical composition and its fluctuation on the microstructure and properties of PHSS are elaborated. Then, the microstructure and properties under a typical heat treatment regime are discussed, including the precipitation of B2-NiAl particles, Cu-rich clusters, Ni3Ti precipitates, and other co-existing precipitates in PHSS and the hierarchical microstructural features are presented. Next, the microstructure and properties after the selective laser melting fabricating process which act as an emerging technology compared to conventional manufacturing techniques are also enlightened. Thereafter, the development of multi-scale simulation and machine learning (ML) in material design is illustrated with typical examples and the great concerns in PHSS research are presented, with a focus on the precipitation techniques, effect of composition, and microstructure. Finally, promising directions for future precipitation hardening stainless steel development combined with multi-scale simulation and ML methods are prospected, offering extensive insight into the innovation of novel precipitation hardening stainless steels.

The possibility of forming a TiN dispersed composite layer on steel was studied by preplacement of titanium powder on steel surface and melting under TIG (Tungsten inert gas) torch in a reactive environment. The surface melting of preplaced 1.8 mg/mm2 Ti powder was performed under TIG torch with energy inputs of 324,378 and 432 J/mm in a pure nitrogen environment. With these melting conditions, the powder layer along with a thin layer of the substrate melted and produced a melt pool of around 1mm thickness. The resolidified melt layer consisted of dispersion of TiN dendrites in ferrite matrix and thus a composite of TiN in ferrite is created on the steel surface. The concentration of dendrite population was found to be higher nearer the melt surface compared to the deeper depth. A maximum surface hardness of about 2000 Hv was developed at the surface when glazed with an energy input of 432 J/mm and the hardness decreased gradually away from the surface. The hardness development is directly related to the concentration of TiN dendrites.
