Abstract Scope |
Refractory alloys are candidate materials for future high temperature aerospace applications, since many of these new environments exceed the temperature limits of state-of-the-art nickel superalloys. Exotic and commercially available refractory alloys may be single or two phase in nature. Thus, the dominant high temperature strengthening mechanisms are not only a function of temperature and strain rate but composition as well. In addition to these considerations, new processing methods have demonstrated the capability of refining grain structures which will also affect performance. This study will provide a detailed analysis of the defects governing the high temperature plastic deformation and the associated substructures of refractory alloys in light of electron backscatter diffraction and transmission electron microscopy observations. These observations will also be assessed with respect to computational models that incorporate key microstructural features and chemical phenomena to predict mechanical performance at various length scales. |
