Semchyshen, M; Barr, R Q

Studies of the mechanical properties of wrought Mobase alloys were extended to include Mo--Hf binaries, a promising Mo-- Ti-- Zr ternary, and one Mo- - Ti-- Zr-- Hf quaternary. The studies included micrography, hightemperature hardness, recrystallization, grain coarsening tendencies, tensile tests, brittle to ductile transition, and creep-rupture tests. Investigation of the mechanism of strengthening in the Mo-- Ti system continued. The alloy systcms Mo-- Ti, Mo-- Nb, Mo-- Zr, and Mo-- Hf were studied as to their preparation, structure, hrdness, oxidation rates, forgeability, and recrystallization. The metallography and x-ray fluorescence techniques used are described. (T.R.U)
