"Breakthrough Discovery: Diamond's Rapid Defect Spread Defies Sound Barrier"

Researchers have discovered that linear defects, known as dislocations, can propagate through materials faster than sound waves. Using X-ray radiography, scientists measured the speed of dislocations spreading through diamond and found that they travel faster than the transverse speed of sound. This finding has implications for understanding material failure and damage in extreme conditions. The study provides new insights into the behavior of dislocations and challenges previous assumptions about the fastest possible materials failure.
