Abstract : The authors examined the mechanical properties and the sensitivity to concentration of stresses of alloys of the Ti-Ta-Mo system which contain 1.6, 4.8, and 8.0 Ta and Mo with a ratio of Ta: Mo = 1:1 in a temperature range of from plus 20 to minus 253 degrees. An alloy with an alpha solid solution structure is highly plastic at low temperatures, and two-phase alpha + beta alloys with a small amount of dispersion beta phase possess a sufficient reserve of ductility with high strength.
