Abstract:

TITANIUM ALLOYS ARE OF GREAT INTEREST IN THE AEROSPACE INDUSTRY BECAUSE OF THEIR SPECIFIC STRENGTH, GOOD FRACTURE RELATED BEHAVIOR AND GENERALLY BETTER CORROSION RESISTANT BEHAVIOR. THE STRENGTH AND HARDNESS OF TI ALLOYS CAN BE SIGNIFICANTLY INCREASED BY REFINING THE MICROSTRUCTURE THROUGH RAPID SOLIDIFICATION PROCESSING (RSP). ADDITIONAL REFINEMENT OF MICROSTRUCTURE AND A REDUCTION OF FORGING TEMPERATURE CAN BE ATTAINED BY TEMPORARY ALLOYING WITH HYDROGEN. A REDUCED FORGING TEMPERATURE WILL LEAD TO THE PRESERVATION OF REFINED MICROSTRUCTURE OBTAINED BY RSP. IT IS PROPOSED HERE THAT A DETAILED STUDY BE MADE OF THE RESPONSE OF SOME RAPIDLY SOLIDIFIED TI ALLOYS WITH NOVEL ADDITIVES TO HYDROGENATION AND DEHYDROGENATION. THE ALLOYS PROPOSED ARE EUTECTOID FORMERS (TI-4CU) AND COMPOUND FORMERS (TI-1.0B, 1.0C). OPTIMUM PARAMETERS FOR OBTAINING REFINED MICROSTRUCTURE WILL BE SPECIFIED THROUGH A CORRELATION OF THE OBSERVED MICROSTRUCTURE WITH THE ACCURATE MEASUREMENT OF HYDROGEN USING THE HELIUM INDUCED PROTON RECOIL DETECTION TECHNIQUE.
