“…Saito et al [17] developed one of the earliest phase-field formulism based on the Cahn-Hilliard equation to study the phase separation kinetics. From the Saito model, numerous simulations of the kinetics of phase separation for different alloys have been proposed and showed an acceptable fit with experimental results [18][19][20][21][22][23][24][25][26][27][28][29][30]. The results of the phase-field method enable one to follow the microstructure evolution and growth kinetics of polymers, fracture, grain growth, phase decomposition, etc.…”

“…The results of the phase-field method enable one to follow the microstructure evolution and growth kinetics of polymers, fracture, grain growth, phase decomposition, etc. [20][21][22][23][24], not only in binary alloys, but also in ternary and quaternary alloys [18,19,[25][26][27][28][29][30]. Therefore, it seems to be a good alternative for analyzing the phase decomposition in aged Mn-rich Mn-Cu alloys, since no phase-field simulation results are reported in the literature.…”

The spinodal decomposition was studied in the aged Mn-40 at. %Cu, Mn-30 at. %Cu, Mn-20 at. %Cu alloys using a phase-field model based on the Cahn–Hillard equation, considering a subregular solution model and the energy contribution of the magnetic behavior. The simulations were performed at aging temperatures of 300, 400, and 500 °C for times from 1 to 240 min. The growth kinetics of the Mn concentration profiles with time indicated clearly that the phase decomposition of the supersaturated solid solution γ into a mixture of Mn-rich γ′ and Cu-rich γ phases occurred by the spinodal decomposition mechanism. Moreover, the phase decomposition at the early stages of aging exhibited the characteristic morphology of spinodal decomposition, an interconnected and percolated microstructure of the decomposed phases. The most rapid growth kinetics of spinodal decomposition occurred for the aging of Mn-20 and 30 at. %Cu alloys because of the higher driving force. The presence of the phase decomposition is responsible for the increase in hardness, as well as the improvement of the damping capacity of Mn-Cu alloys.

“…They are used for building structures, storage tanks, chemical tanks, pressure vessels, and process equipment. They can be found as a construction material, e.g., in desalination processes, peroxide reactors, fermentation chambers, expansion tanks, pipes, flexible hoses, domestic heating devices, and hot water tanks [ 13 ]. They are good materials for dryers, heat exchangers, structures operating in aggressive environments (e.g., in seawater, H 2 S, CO 2 ), and dynamically loaded devices [ 14 ].…”

The objective of this study was to determine the requirements for steels used as construction materials for chemical apparatus operating at an elevated temperature and to correlate them with the properties of the tested steels. The experimental part examined the influence of the annealing process on the structure and properties of X2CrNiMoN22-5-3 (1.4462) and X2CrNiMoCuWN25-7-4 (1.4501) steel. Heat treatment was carried out on the tested samples at a temperature of 600 °C and 800 °C. Changes were observed after the indicated time intervals of 250 and 500 h. In order to determine the differences between the initial state and after individual annealing stages, metallographic specimens were performed, the structure was analyzed using an optical microscope and the micro-hardness was measured using the Vickers method. Potentiostatic tests of the samples were carried out to assess the influence of thermal process parameters on the electrochemical properties of the passive layer. An increase in the hardness of the samples was observed with increasing temperature and annealing time, the disappearance of magnetic properties for both samples after annealing at the temperature of 800 °C, as well as a significant deterioration in corrosion resistance in the case of treatment at a higher temperature.
