High temperature mechanical behavior of Nb{sub 5}Si{sub 3}/Nb laminates
- Univ. of Michigan, Ann Arbor, MI (United States)
Two phase alloys based on the intermetallic system Nb{sub 5}Si{sub 3}/Nb system provide potentially superior combination of strength and toughness over their monolithic counterparts at high temperatures. To gain fundamental knowledge of the mechanical behavior of these materials, initial focus has been on the mechanical behavior of Nb{sub 5}Si{sub 3}/Nb laminates and composites at elevated temperatures. In this study, laminates have been fabricated at 32 at% Si with Nb, and a total laminate thickness of 2.1 mm. Tests are being conducted on notched and unnotched tensile specimens. The unnotched specimens provide the overall strength and ductility of the laminate and a basis for comparison with notched specimens which provide information on crack propagation and ductile phase toughening effects. Results from samples with a variety of laminate spacings are being explored, and preliminary data will be presented.
