A study of the features of structural-phase state, thermal stability, mechanical properties characteristics and fracture features of V-Cr-Ta-Zr alloy after chemical-heat treatment by the method of nonequilibrium internal oxidation has been carried out. It has been established that, in contrast to chemical-heat treatment in a defect state, the effect of oxygen when introduced into a material with a stabilized structure is observed only at high concentrations. At such oxygen concentrations, which ensure the maximum binding of Zr into particles based on ZrO2, the alloy under study demonstrates a high level of thermal stability and strength properties. These effects are associated with the implementation of disperse strengthening according to the Orowan mechanism by nanosized ZrO2 particles characterized by high thermal stability. The concentration and nature of the distribution of oxygen predetermine the spatial distribution of nanosized ZrO2 particles formed during chemical-heat treatment, which manifests itself in fracture features of the material at different temperatures.

The article presents experimental results on the application of thermal oxidation or low temperature gas nitrocarburizing (LTGNC) of Ecosint powders sintered under industrial conditions. Surface hardness HRB and microhardness (HV0.1) were studied. A structural analysis was carried out and the corrosion resistance of the alloys was investigated. Conclusions were made on chemical heat treatment performed on structure and mechanical properties of the investigated alloys.

The Impact

Any improvement on the service life of tools reduces the tooling costs, and assists to increase labor productivity by decreasing the needs for either the tools’ re-grinding or their replacement. This requires, among others, an enhancement of the key mechanical properties of the tool materials, by newer treatment route development. The current paper describes the impact of different heat treatment regimes, including austenitizing; sub-zero treatments; and tempering on the hardness, flexural strength, and toughness of tool steel, which is demonstrated upon Vanadis 6 steel. An improvement in the hardness due to the sub-zero treatment is reported, but it is also pointed out that both the flexural strength and fracture toughness of the material cannot be inevitably deteriorated by the application of this processing. Finally, it is demonstrated that both of these properties, despite their conflicting relationship, in most cases, can be improved simultaneously when the material is treated in the proper way.

Heat Treatment Regimes

The paper provides the results of statistical research of the mechanical properties of deformed semi-finished titanium alloys Ti-6Al-4V and Ti-10V-2Fe-3Al, based on the industrial data analysis. The research objects were 1.635 forging products, made of the alloys ВТ6 (Ti-6Al-4V) and Ti-10-2-3 (Ti-10V-2Fe-3Al), manufactured in compliance with the industrial technology. The statistical research conducted with the help of the applied software package "Stadia 7" included the primary statistical manipulation and a correlation-regression analysis with the help of standard methods. The authors established correlation relationships between the mechanical properties of such semi-finished products containing alloying elements, admixtures and the industrial modes of the strengthening heat treatment. It was revealed that the variations in the grade composition, hardening and aging temperature can determine 10-40% of variable forging mechanical properties. The key variation is pre-determined by the factors the authors failed to identify on the basis of the data research.
