Failure Analysis of a Metal Fastener

Have you ever had a fastener fail? This video discusses fastener failure analysis. In this case a steel fastener fractured less than one week after it was installed. The failure analysis included these analyses:
Scanning electron microscopy (SEM)
Energy dispersive x-ray spectroscopy (EDS)
Metallography
Microhardness testing
The analysis results, fracture mode, and root cause of the failure are discussed in the video. If you want to learn more about failure analysis check out our website www.imetllc.com/failure-analysis/

Hi, how about failure analysis on fasteners that easily on the surface of the metal fasteners after heat treatment ? Thank Youu

Good video. Beach marks on a broken bolt indicate a ductile fracture or fatigue fracture? Thanks

[@deanliu2288]

beach mark is typical feacture of fatigue fracture. Ductile fracture is a kind of overload failure mode
