reportActive / Technical Report | Accession Number: ADA136036 | Need Help?

Abstract:

The work on this program consisted of three parts study of fatigue crack propagation behavior of alpha-beta Ti-Mn alloys rationalization of the role of microstructure in the fracture toughness of the alpha-beta alloy Ti-5.25Al-5.5V-0.9Fe-0.5Cu and n examination of slip transfer from alpha - beta. A summary of the achievements in each of these areas and pertinent additional information will be given in the following presentation.
