Investigation of the liquid-liquid miscibility gap in the Cu-Co-Zr-system — •Björn Schwarz, Norbert Mattern, and Jürgen Eckert — Leibniz Institute for Solid State and Materials Research, Dresden, Germany

For a variety of compositions Cu-Co-Zr prealloys were rapidly quenched by splat-quenching and melt-spinning technique. Concerning the chemical homogeneity, phase constitution as well as amorphicity, that are all essentially influenced by a liquid-liquid miscibilty gap found for this system, the samples were investigated by DSC, SEM, HAADF STEM/HRTEM and XRD. Especially those samples partially exhibitng the (Co/Cu)Zr-phase (B2) with martensitic transformation at low temperature show interesting physical properties that were characterized by measurements of the magnetization and electric conductivity.
