Sometimes, through no fault of their owners’ use, gun parts simply fail. In many cases, “fatigue failures” are to blame. Can they be predicted? A veteran firearm engineer answers that question.

This is due to what's called metal fatigue, which occurs when a metal component is cyclically stressed until it ... along with new ultrasonic fatigue testing and multimodal data analysis techniques.

Such analysis is helpful for identifying alloys that show exceptional or unusual behaviour and provides a different approach for identifying fatigue-resistant alloys quickly and simply, he adds. The ...

Abnormal wear debris from abrasion, adhesion, and fatigue consists of large particles containing base metals. Microspall ...

The cockpit voice recorder and flight data recorders were shipped for analysis to NTSB facilities in Washington, D.C. Two of the 22 fan blades on one of the Pratt & Whitney engines were damaged.

To overcome the issue of low fatigue resistance in 3D-printed alloys and generally in all metal materials, a joint-research team of CityU and Shanghai Jiao Tong University used Laser Powder Bed Fusion ...

A National Institute for Materials Science (NIMS) research team has identified the mechanism by which microscopic fatigue cracks grow in metals, solving a half-century-old mystery. The team found ...
