The phase composition and structure of cold-worked and annealed (at 500, 700, and 1000°) Nb-30-50% Zr alloys are studied by x-ray methods and in the electron microscope. As a result of a decomposition at 500° an Nb-base bcc solid solution and a solid solution of Nb in α-Zr with a hexagonal lattice are formed. Annealing at 700° causes decomposition into two bcc solid solutions. Annealing at 1000° causes recrystallization of the alloys, taking place most completely in that containing 50% Zr.
