Abstract
2 C. This rapid consolidation process inhibits grain growth and ensures high strength and ductility of the consolidated material. Microstructure of the consolidated material was characterized via optical microscopy, scanning electron microscopy and energy dispersive spectroscopy. The average grain size of the consolidated specimen (calculated via the line- intercept method) was found to be 10 micrometers indicating that no grain growth occurred during consolidation. The microstructures showed relatively full densification with no apparent porosity. The flexure strength and elastic modulus in bending were measured to be 684 MPa and 180 GPa, respectively at room temperature (RT). The Vickers hardness was measured to be 2.7 GPa at RT. The flexure strength and elastic modulus remained constant from RT to 600 o C.
