The phase equilibria in the CuAlZr system at 1073 K up to 50 at.% Al


The phase equilibria in the CuAlZr system at 1073 K were investigated by X-Ray and elektron-probe microanalysis methods, in the Zr-rich region. The fragment of isothermal section of the given system was constructed. The homogeneity regions based on phases τ4 and τ5 of ternaries ZrCu2Al and ZrCuxAl2x were investigated. The character the phase equilibria between double and threefold compounds of the AlCuZr system was established.It was found out that at the Zr concentration above 55 at.% of threefold compounds are not formed, and the phases Zr3Al and Zr2Cu are in equilibria with α-Zr at 1073K.
Key words: phase equilibria, X-Ray analysis and elektron-probe microanalysis, bulk amorphous alloys
