Nitrogen absorption behavior and mechanism of TiZrMnFe getter alloy

Lei Li et al.

Summary: The getter alloy of TixZr1-xMnFe(x = 0, 0.1, 0.2, 0.3, 0.4) was prepared and its nitriding behavior was studied, showing that nitrogen absorption amount increases while absorption rate slows down with the substitution of Ti. The nitrogen absorption process involves surface N-2 absorption and dissociation, nitrogen atom diffusion, formation of (Zr,Ti)N phases, and growth of (Zr,Ti)N particles into saturated barriers.

Gas nitriding of a plasma detonation modified die steel

Jin Zou et al.

Summary: The study found that the plasma detonation technique (PDT) significantly affected the nitrided layer on AISI H13 steel, forming a modified layer. Grinding off the melted layer resulted in a 40% increase in nitrided layer thickness.

High-resolution topochemical analysis and thermochemical simulations of oxides and nitrides at grain boundaries and within the grains of a low alloy Mn-Cr hot-rolled steel sheet

Vera G. Praig et al.

Summary: The selective oxidation process of industrially hot rolled Fe-1.8Mn-0.8Cr steel at temperatures between 600 and 700 degrees C was investigated, revealing heterogeneities in chemical composition, especially along grain boundaries, through high-resolution topochemical analysis. Experimental results showed that grain boundary oxides are mainly composed of aluminum, chromium, or silicon oxides/nitrides, surrounded by manganese-rich oxides.

The microstructures and mechanical properties of martensite Ti and TiN phases in a Ti6Al4V laser-assisted nitriding layer

Penglin Zhang et al.

Summary: The research finds that the nano-hardness of the TiN phase is 2609 HV with an elastic modulus of 208 GPa, while the nano-hardness of alpha '-Ti is 632 HV with an elastic modulus of 142.8 GPa. The entanglement of two sets of parallel dislocations in alpha'-Ti crystals forms subgrain boundaries, exerting a positive influence on work hardening and fine-grain strengthening. During the TiN dendritic fracture process, a crack-toughening mechanism occurs with primary dendrites undergoing near ductile fracture along the growth direction of secondary dendrites.

Investigation of nitrogen ionization state and its effect on the nitride layer during fiber laser gas nitriding of Ti-6Al-4V alloy

Jinchang Guo et al.

Summary: During fiber laser gas nitriding of titanium alloys, the nitrogen ionization state influences the formation of nitride layer, with differences in reaction rates and nitrogen content due to the energy disparity between nitrogen molecules and nitrogen plasma. This ultimately affects the surface morphology and quality of the nitride layer.
