| Abstract Scope |
TZM is a molybdenum-based refractory alloy used in high temperature applications, and may be subjected to mechanical deformation during service. As such, the quasi-static and dynamic material properties are of great interest. Here we present data on deformation and failure of several TZM materials over a range of conditions, both quasi-static and dynamic. Of particular interest, Kolsky bar was used to measure high rate stress-strain response of these materials, possibly for the first time. This data is incorporated into a rate-sensitive deformation model. Materials were characterized using electron backscatter diffraction (EBSD) to observe and quantify crystal orientations and microstructural features (especially textures) to link thermomechanical processing to observed behavior. Fractography suggests an unconventional failure mode, which will be discussed. Additionally, a brief introduction to a new method of Kolsky bar analysis (the open-source HopPyBar code) will be presented. |
