“…Here, since the crystallography of Al 80 Cr 20 is unclear and hence can not be confidently related to the equilibrium phases of Al-Cr 49 , we can not account properly the (relative) stability of this phase. One possible assumption would be that Al 80 Cr 20 represents Al 4 Cr, but even Al 4 Cr is not observed in the current deterministic evaluation.…”

“…Competing phases consist of the MAX end-members and other intermetallic compounds that have been observed or proposed in previous literature on the phase stability of Ti 2 AlC-Cr 2 AlC. In addition, we also considered the compounds from the assessed phase diagrams of Ti-Cr 46 , Ti-Al 47 , Ti-C 48 , Cr-Al 49 , Cr-C 48 , and Al-C 48 . Table 1 summarizes the competing compounds that we consider in the current work.…”

The quest towards expansion of the Mn+1AXn design space has been accelerated with the recent discovery of several solid solution and ordered phases involving at least two Mn+1AXn end members. Going beyond the nominal Mn+1AXn compounds enables not only fine tuning of existing properties but also entirely new functionality. This search, however, has been mostly done through painstaking experiments as knowledge of the phase stability of the relevant systems is rather scarce. In this work, we report the first attempt to evaluate the finite-temperature pseudo-binary phase diagram of the Ti2AlC-Cr2AlC via first-principles-guided Bayesian CALPHAD framework that accounts for uncertainties not only in ab initio calculations and thermodynamic models but also in synthesis conditions in reported experiments. The phase stability analyses are shown to have good agreement with previous experiments. The work points towards a promising way of investigating phase stability in other MAX Phase systems providing the knowledge necessary to elucidate possible synthesis routes for Mn+1AXn systems with unprecedented properties.

“…In these reviews, liquidus surfaces, various complete and partial isothermal sections in the temperature range 770 -1473 K, and reaction schemes were presented. Three thermodynamic descriptions of the ternary AlTi-Cr system [21][22][23] have been developed based on extensive literature reviews of existing phase equilibria data. However, the construction of the solidus projection as well as the analysis of the phase equilibria just below the solidus temperatures for Al contents < 75 at.% was not presented yet.…”

Retrieved surface layer, which is fine-dyspersated carbide composite structure area which has a higher microhardness and sufficient ductility. It is used for parts that are in friction pairs under conditions of dynamic loads. Some parts that require high resource work, reinforcing coating applied to high thickness -300 µm. Such details can be processed several times during their gradual deterioration. Work surface heavily loaded parts operating at high unit pressures are applied coating reinforced, composite zone, there is a high content of chromium carbides and large microhardness.The presence of Ni content in the homogeneous zone positively influences the work of such details.
