Abstract
TITANIUM ALLOYS WITH IMPROVED HIGH TEMPERATURE CAPABILITIES ARE OF STRONG INTEREST TO THE U.S. AIR FORCE FOR POTENTIAL MILITARY APPLICATIONS. RAPID SOLIDIFICATION TECHNOLOGY (RST) OFFERS EXCELLENT PROSPECTS FOR CREATION OF NEW STRUCTURAL ALLOYS WITH SUPERIOR PROPERTIES NOT ACHIEVABLE BY CONVENTIONAL METALLURGY. MARKO MATERIALS UNDER THE PROPOSED PHASE I INVESTIGATION INTENDS TO DEVELOP A NEW METHOD BASED ON MELT-SPINNING FOR MANUFACTURING POWDERS OF DIFFICULT-TO-PROCESS TITANIUM ALLOYS. USING THIS PROCESS, MARKO WOULD EXPLORE NEW TITANIUM ALLOYS WITH GOALS TO ACHIEVE IMPROVED HIGH TEMPERATURE PROPERTIES VIA THE DISPERSION HARDENING EFFECTS OF TITANIUM BORIDE PHASES. CONVENTIONAL ALPHA AND ALPHA-BETA ALLOYS MODIFIED WITH 1-2 PERCENT BORON WILL BE RAPIDLY SOLIDIFIED INTO METASTABLE PHASES. UPON DECOMPOSITION OF AS-SOLIDIFIED PHASES AT HIGH TEMPERATURES DURING CONSOLIDATION PROCESSING, A THERMALLY STABLE DISPERION OF BORIDE PHASEES IN A FINE GRAINED MATRIX WILL BE GENERATED. SUCH MICROSTRUCTURES WILL LEAD TO IMPROVED TENSILE, CREEP, AND FATIGUE PROPERTIES AT ELEVATED TEMPERATURES.
