Phase and properties prediction of Al–Ag binary system using thermo-calc

The temperature phase diagram stability and physical properties of a binary Silver–Aluminium (Al–Ag) alloy system have been calculated using Thermo-Calc 2021b software at a temperature range of 250–1300 K. Six single-solid phases other than the liquid phase, elemental Ag (fcc_Ag), elemental Al (fcc_Al), hcp_A3, cub_A13, and bcc_Ag were obtained from the equilibrium calculation. Ten regions of the double phase were obtained and evaluated. Three intermediate phases were also obtained from the phase diagram with five invariant reactions, namely one eutectic reaction (at 840.00 K), two peritectic reactions (at 1051.22 K and 1003.18 K), and two peritectoid reactions (at 730.58 K and 881.40 K) were equally found. Sixteen regions other than elemental Ag and Al at 0, and 100, respectively, were obtained. Maximum solid solubility obtained was 5.60 Al mass percent at 730. 58 K for Al in Ag and 58.17 Ag mass percent at 840.00 K for Ag in Al. From the temperature–composition phase diagram, the melting point for pure silver and aluminium were equally inferred as 1234.96 K and 933.50 K, respectively, which agrees with experimental standards. These results play a significant role in the processing of Al–Ag alloy for different industrial-related applications. Graphical abstract: [Figure not available: see fulltext.]
