| Abstract Scope |
Single-phase body-centered cubic (BCC) molybdenum-rhenium (Mo-Re) alloys exhibit a desirable combination of properties for high-temperature and demanding applications, provided appropriate processing conditions maintain a single-phase structure. The alloy’s composition and processing parameters—particularly heat treatment temperature and duration—strongly influence its microstructure and, consequently, its mechanical response. Texture plays a critical role in determining the mechanical behavior of single-phase Mo-Re alloys and is notably affected by thermomechanical processing and rhenium content. To gain a comprehensive understanding of how composition and processing shape deformation behavior, we employ a combination of mechanical testing (quasi-static and dynamic) and electron microscopy. Our discussion emphasizes results from Electron Backscatter Diffraction (EBSD) analysis, which we use to investigate differences in deformation mechanisms by examining the evolution of crystallographic texture, dominant deformation modes, and dislocation density distributions under mechanical loading. |
