[Diamond "turns" into graphite in seconds under ultra-high-speed impact] On November 11, a research team from Texas A&M University and Rice University in the United States discovered that under the impact of a projectile with a speed exceeding 8 times the speed of sound, some areas of a diamond composite material will undergo a rapid phase change and turn into graphite within a few microseconds. This discovery is expected to provide new ideas for the future research and development of aerospace, national defense and protective materials. The relevant paper was published in the latest issue of "Materials Today" magazine.
