Rice University Develops Technique to Stabilize Diamond During Thermal Processing for Aerospace Applications

Researchers at Rice University have developed a new manufacturing technique that stabilizes diamond during thermal processing at low pressures, resulting in a durable composite material. This advancement, detailed in Materials Today, demonstrates how combining powder materials can overcome previous manufacturing challenges, particularly in creating tougher materials for aerospace and defense applications. The significance of this research lies in its ability to transform diamond into graphite in millionths of a second under hypersonic projectile strikes, a rapid phase change that absorbs kinetic energy. Abhijit Biswas, the study's first author, noted that the resulting composite is nearly nonmachinable and tough, making it suitable for extreme conditions faced in various technologies. Looking ahead, the team utilized spark plasma sintering to create a composite where diamond grains are embedded within a cubic boron nitride structure, offering a practical method for large-scale production of diamond-based parts. Future studies may focus on further evaluating the mechanical limits of this composite and its potential applications in high-performance environments. No further timeline was disclosed at the time of publication.
