Experimental and thermodynamic assessment of the Gd-Zr system

▸ A new Gd-Zr phase diagram is presented. ▸ In situ XRD was combined with levitation to study liquid phase equilibrium. ▸ The eutectic reaction was observed L↔bcc-Gd+bcc-Zr at T=1495 K. ▸ The coexistence of bcc-Gd and bcc-Zr is measured for 1450 K
