摘要: Abstract A novel technique for fabricating high-temperature molybdenum–silicon–boron intermetallic composites is described. Vacuum annealing of silicide particles resulted in a loss Si, and consequently Mo solid solution layer, at the surfaces. Subsequent consolidation produced microstructure bonded by continuous matrix. The α-Mo imparted significant room temperature fracture toughness.
