Rice University researchers have discovered that diamond can rapidly transform into graphite when subjected to high-speed collisions, a process that absorbs massive amounts of energy. The team also developed methods to stabilize diamond during high-temperature and low-pressure processing to create strong bulk composite materials. This phase transformation from diamond to graphite under extreme impact conditions occurs nearly instantaneously.


This discovery has significant implications for designing advanced protective materials and armor systems that could absorb enormous amounts of kinetic energy through controlled diamond-to-graphite transformation. The ability to stabilize diamond in composite materials at lower pressures and high temperatures could also enable new manufacturing approaches for ultra-strong materials.


Rice University researchers have developed a way to stabilize diamond during high-temperature and low-pressure processing, creating a strong bulk composite and discovering that high-speed collisions can rapidly transform diamond into graphite. Their study is published in Materials Today.
