Abstract
TITANIUM ALLOYS ARE OF GREAT INTEREST IN THE AEROSPACE INDUSTRY BECAUSE OF THEIR HIGH SPECIFIC STRENGTH, GOOD FRACTURE RELATED BEHAVIOR AND GENERALLY BETTER CORROSION BEHAVIOR. MAGNESIUM ALLOYS ALSO HAVE BEEN CONSIDERED FOR AEROSPACE APPLICATIONS BECAUSE OF THEIR LIGHT WEIGHT. HOWEVER, THEIR POOR CORROSION RESISTANCE AND MECHANICALBEHAVIOR HAVE RESTRICTED THEIR USE. FURTHER WEIGHT REDUCTION OF TI ALLOYS AND IMPROVEMENT IN CORROSION AND MECHANICAL BEHAVIOR OF MG ALLOYS REQUIRE RESEARCH OF NEW ALLOYS BASED ON THESE MATERIALS. IT IS PROPOSED TO MEET THESE OBJECTIVES BY DEVELOPING TI-LI, TI-MG, MG-CR AND MG-AL ALLOYS. CONVENTIONAL ALLOYING TECHNIQUES CANNOT BE APPLIED TO FABRICATE MOST OF THE PROPOSED ALLOYS OVER A COMPOSITION RANGE. THEREFORE, A NOVEL TECHNIQUE BASED ON VAPOR DEPOSITION AND SUBSEQUENT ION IRRADIATION HAS BEEN PROPOSED. IT IS EXPECTED THAT THIS TECHNIQUE WILL ENABLE THE FABRICATION OF THE PROPOSED ALLOYS WITH AN AMORPHOUS OR FINE GRAIN MICROSTRUCTURE. TRANSMISSION ELECTRONMICROSCOPY WILL BE USED TO ANALYZE THE MICROSTRUCTURAL DETAILS. POTENTIODYNAMIC POLARIZATION MEASUREMENTS WILL BE CARRIED OUT ON FABRICATED MG ALLOY FILMS FOR EVALUATION OF THEIR CORROSION BEHAVIOR.
