Paragraph starter
The development of ultra-high-temperature materials like Mo-Si-B alloys is often constrained by processing challenges, particularly their inherent brittleness. While compositional modifications like metal doping and the addition of second-phase particles have been explored, their impact on room-temperature fracture toughness remains limited. Furthermore, additive manufacturing techniques, while offering design flexibility, have shown a tendency to introduce significant crack density in these alloys. This review suggests that oscillatory sintering presents a promising alternative manufacturing approach, potentially mitigating porosity and thereby enhancing the critical fracture toughness of Mo-Si-B alloys for advanced applications.
