Supersonic speed weakens metal bonds, strength peaks at 1,060 m/s, study finds
SMRTR summary
Cornell University researchers found metal particles bond optimally at a specific supersonic speed, with bond strength peaking at 1,060 meters per second and declining significantly by 1,337 meters per second. This limit is due to "intensified elastic recovery," where particles bounce back after impact. The findings could improve manufacturing processes like cold spray coating and additive manufacturing by addressing erosion and enhancing material strength.
