Intermetallic Compound Growth and Stress Development in Al-Cu Diffusion Couple

On the competition between synchronous oxidation and preferential oxidation in Cu-Zr-Al metallic glasses

“…8) [12,51]. Possible binary Cu-Zr and Cu-Al intermetallic phases in the corresponding compositional range, as well as their Gibbs energies of formation (ΔGf) [37,57], are collected in Table 4 (as derived from thermodynamic assessments of Cu-Zr [62] and Cu-Al binary alloys [63]). The Cu9Al4 phase is thermodynamically preferred (having the lowest ΔGf of -760.5 kJ/mol Al at 300 °C; see Table 4).…”

Microstructure and Mechanical Properties of Cu–Al Alloy Deposited by Additive Manufacturing

“…Further, it has been found that addition of microalloying elements in Cu-Al alloy can enhance their mechanical properties significantly [3,15]. Several investigations on growth kinetics of intermetallic compounds such as, CuAl 2 , Cu 9 Al 4 , Cu 3 Al in Cu-Al cast alloys have been reported [16][17][18][19]. However, at present, no report is available on detailed microstructural analysis such as, distribution of microalloying elements and formation of intermetallic phases in Cu-Al alloy fabricated by WAAM process.…”
