Open Access Microstructure Evolution of Ruthenium During Vacuum Hot Pressing : Obtaining fine-grained metal with mechanical properties close to electron-beam melted ruthenium

Ruthenium tablets with mean grain size of ~4‐5 μm were prepared by vacuum hot pressing (VHP), and tablets with maximum density of 12.2 g cm‐3 were obtained with sintering time of 2 h. X-ray diffraction (XRD) revealed that there was a texture change with sintering time. The microstructure of the ruthenium tablets was observed by electron backscatter diffraction (EBSD) and field emission scanning electron microscopy (FSEM). The microstructure evolution of ruthenium with sintering time is discussed.
