“…Therefore, the thermodynamic parameters of the Al 9 FeNi phase were slightly modified in our previous work. [39] Thermodynamic assessments have been performed for the Al-Fe-Si ternary system several times. The most recent assessment over the whole composition range have been done by Du et al [6] Eleno et al [40] recently reassessed the Al-rich phase equilibria of the Al-Fe-Si system and refined the descriptions of a-AlFeSi, b-AlFeSi, s 2 -AlFeSi and s 4 -AlFeSi within the COST507 database.…”

However, the Al-Fe-Si description in the COST507 database is relatively outdated compared with that of Du et al [6] A further thermodynamic reassessment of the Al-Fe-Si system in the Al-rich corner was carried out in our previous work [39] based on the work of Du et al [6] For the Al-Mg-Si system, a thermodynamic optimization was carried out by Feufel et al, [41] which was included in the COST507 project. Lacaze and Valdes [42] modified slightly the description of the liquid phase in the Al-MgSi system with respect to the COST 507 data.…”

“…Since the review of the experimental phase equilibria of the Al-Fe-Ni-Si system have been reported by our previous work, [39] they are briefly presented here. Gusev [57] and Belov [58] employed about 80 quaternary alloys to study the microstructure, phase composition, and thermograms of cast and heat-treated alloys, which were reviewed and summarized in detail by Belov et al in 2002 [59] and 2005.…”

“…[ 39] The related phase equilibria, phase transition temperatures, and solidified microstructure were determined in both annealed and as-cast alloys by means of XRD, SEM/EDX, EPMA, TEM and DTA techniques. On the basis of the experimental equilibria from the present work and the literature, a set of self-consistent thermodynamic parameters for the quaternary Al-Fe-Ni-Si system in Al-rich corner was simultaneously obtained and adopted in the present work.…”

Based on the critical review of the available experimental phase equilibrium data for the constituent quaternary systems in the Al-Fe-Mg-Ni-Si and Al-Cu-Fe-Mg-Ni quinary systems, a set of self-consistent thermodynamic parameters for these systems has been obtained using the CALPHAD approach. In combination with the constituent binary, ternary and quaternary systems, the thermodynamic database for the quinary Al-Fe-Mg-Ni-Si and Al-Cu-Fe-Mg-Ni systems was developed. Comprehensive comparisons between the calculated and measured phase diagrams and invariant reactions showed that the experimental data were satisfactorily accounted for by the present thermodynamic description. The established database was used to describe the solidification behaviors of Al alloys 6063 (Al-0.39Si-0.20Fe-0.43Mg, in wt.%) and 2618 (Al-2.24Cu-1.42Mg-0.9Fe-0.9Ni, in wt.%) under Gulliver-Scheil non-equilibrium condition. The reliability of the present thermodynamic database was also verified by the good agreement between the Gulliver-Scheil calculation and experiment.

“…Ni and Si are also ones of the major alloying elements in Al alloys. In our effort to develop a thermodynamic database for multi-component Al-alloys [2][3][4][5][6], it is realized that a more accurate thermodynamic description of the Mn-Ni-Si system is needed along with three constitutive binary systems.…”

Iased on the new experimental data available in the literature, the Mn-Ni-Si system has been reassessed using the CALPHAD (CALculation of PHAse Diagram) approach. Compared with the previous modeling, the ?8 and ?12 ternary phases were treated as the same phase according to the new experimental data. The Mn3Si phase was described with two sublattice model (Mn, Ni)3(Si)1. The reported new ternary phase ? was not considered in the present work. Comprehensive comparisons between the calculated and measured phase diagrams showed that a set of thermodynamic parameters of the Mn-Ni-Si system obtained in this work was more accurate than the previous one.

Abradable systems are used in the aeronautical industry to improve the efficiency of gas turbine. Those materials are exposed in service to temperature up to 450 °C. The increase in gas turbine efficiency requires to increase the operating temperature and therefore the service temperature of abradable coating. The present study focuses on the isothermal and cyclic thermal aging of the Al–Si abradable coating system in a laboratory air at high temperature up to 500 °C. The investigation encompasses the microstructural evolution, phase transformation, and the formation of cracks, along with their interrelated effects. During aging, silicon particles precipitate in the abradable top coat. In addition, coarsening of those particles is observed and the coarsening kinetics appears to be faster in cyclic thermal aging conditions compared to isothermal aging. During cyclic and isothermal aging, brittle aluminides develope at the abradable top–coat/bond–coat interface, due to the interdiffusion of Al and Ni species. During cyclic aging, thermal cycles create thermomechanical stress at the top‐coat/bont‐coat interface due to coefficient of thermal expansion mismatch between the Al‐Si deposit and intermetallic phases. The stress generated results in the formation of cracks and porosities at the top–coat/bond–coat interface resulting in a dramatic failure of the system.This article is protected by copyright.
