ATOMIC ARRANGEMENTS IN TITANIUM-MOLYBDENUM SOLID SOLUTIONS
Abstract
The short range order and size effect coefficients as well as the thermal and static atomic displacements have been measured in bcc solid solutions of Ti-Mo using X-ray diffraction techniques. These solutions exhibit a strong preference for unlike near-neighbors even though a superlattice was not found. The size effect coefficients for the first shell of atoms were negative, indicating that the Mo atoms were smaller than the Ti atoms in solution. Centerto-center distances between the different pairs of nearest neighbor atoms were calculated from the size effect coefficients and the lattice parameters. Ti-Ti and Mo-Mo distances tended to approach the average distance in the solution at compositions between 20 and 50 at-% Mo. At 75% Mo the Mo-Mo distance was smaller than in pure Mo and this was taken to indicate an electron exchange in the solution. (Author)
