Title: RESEARCH ON THE EFFECTS OF STRESS, STRAIN, AND TEMPERATURE ON THE EUTECTOID DECOMPOSITION OF TITANIUM ALLOYS. Period covered February 1, 1956 to May 30, 1957

Abstract

Three Ti--Cr alloys were forged in the alpha - BETA range to give six systems with cortrolled amounts of each phase. The isothermal transformation at 400, 500, and 6OO deg C of each of these systems was followed by resistivity, x- ray diffraction, elastic modulus measurements, and metallography. The reactions occurring in the transformation were identified where possible. This transformation study was repeated under a stress which produced 1% creep in 1OOO hr. An acceleration of four to seven times in the rate of transformation occurred under tbe action of this stress. Complete tensile test data were obtained at all stages of the transformation and plotted on the T-T-T dingrams. These reveal that the formations of omega and TiCr/sub 2/ are the embrittling reactions. The eutectoid temperature in the Ti-- Cr system was determined to be 670 deg plus or minus 5 deg C. (auth)
