Abstract Scope |
Molybdenum-rhenium (Mo-Re) alloys are an important class of materials for a lot of extreme environments, including high temperatures. Rhenium addition to Molybdenum increases the ductility, toughness, and recrystallization temperature. In this investigation the Hardness, Modulus, Strain rate sensitivity, creep, stress relaxation, and response to Dynamic Mechanical Analysis was examined for several Mo-Re and other Mo alloys.
Nanoindentation is particularly useful in this investigation because it allows precise measurement of mechanical properties at very small scales, providing insights into how Rhenium affects the local mechanical response of the alloy. By systematically examining these various rhenium concentrations in molybdenum and performing nanoindentation tests, correlations between composition, microstructure, and mechanical properties can be established. |
