Experimental study of the Al–Cu–Zn ternary phase diagram
Source abstract
Abstract
Abstract The phase diagram of the Al–Cu–Zn ternary system was re-investigated experimentally. The current study was designed to contribute to a better description of those parts of the phase diagram, which are disputed in the current scientific literature. Mutual relations in the family of ternary intermetallic phases τ with cubic, rhombohedral and modulated structure at temperatures 400 °C and 550 °C were described. The phase relation between the γ and γ′ phases was studied at different temperatures. A two-phase field between γ and γ′ was observed below 400 °C, while the transition appears to be second order at higher temperatures. A vertical section between γ and γ′ phases in Cu–Zn and Al–Cu and four isothermal sections at 400 °C, 550 °C, 700 °C and 820 °C, respectively, were constructed.
