Effect of Zr on Microstructure and Mechanical Properties of the Al–Cu–Yb and Al–Cu–Gd Alloys
The effect of zirconium on the microstructure, phase composition, and mechanical properties of AlCuYb and AlCuGd alloys was studied. The microstructure of the as-cast alloys did not consist of new intermetallic phases of zirconium with other elements, so

Separation of Zirconium and Hafnium from Chloride Solution Using Strongly Basic Anion Resins [PDF]
The ion exchange process was employed to separate zirconium from hafnium in solution. To this end, four effective parameters, involving resin type, HCl concentration, Time, and initial zirconium concentration, were selected as the main variables.
