Abstract
THE existence of α-manganese phases in the zirconium–technetium, niobium–technetium and molybdenum–technetium systems was recently reported by V. B. Compton et al.1. During the course of our investigation of alloy phases involving technetium-99 with transition metals, α-manganese phases were found in the binary systems scandium–technetium, titanium–technetium, hafnium–technetium and tantalum–technetium. Pertinent information is given in Table 1. The alloys were made by arc-melting transition metals of high purity with technetium-99. X-ray data were obtained from specimens in the as-cast condition with a powder camera of 114.6 mm. diameter using filtered copper radiation.
