THE TITANIUM-NIOBIUM SYSTEM
An examination was made on the formation and aging characteristics of a martensitic alpha phase obtained in Nb-- Ti alloys by quenching. The structure of the transformed alloys was determined by x-ray diffraction using waterquenched solid specimens, approximately 1 cm across. The structures of alloys containing more than 5 at.% Nb were anomalous. Many of the reflections from the alpha phase were split into two components the separation of which increased with increasing Nb content. The observed diffraction pattern is best interpreted in terms of a c-centered onthorhombic cell, which can be regarded as a simple distortion of the hexagonal cell of alpha -titanium. There was no evidence for segregation of Nb to special sites. Cell dimensions and diffraction data are tabulated. (P.C.H.)
