THE DETERMINATION OF THE EQUILIBRIUM PHASE DIAGRAM, ZIRCONIUM-NIOBIUM. Interim Report No. 1

Technical Report ·
OSTI ID:4048778
;
The phase relationships were determined by metallographic techniques with the auxiliary aid of hardness determination and incipient-melting techniques. A minimum in the liquid-solid boundaries occurs at 22 wt% niobium and 1740C. Complete solid solubility exists above 970C in the body-centered cubic phase. A monotectoid reaction exists at 20 wt% niobium and 610C:. Solid solubilities at the monotectoid level are 0.6 and 85 wt% niobium, respectively. (auth)
