Widespread cadmium (Cd) whisker growth has recently been observed in a survey of Cd plated low-alloy steel fasteners used in high-reliability components. Whiskers were found on the fastener threads and head (both inside the socket and on the underside of the head); the most worn and debris covered areas exhibited the most dense whisker growth. The debris on the threads was identified through energy dispersive X-ray spectroscopy (EDS) as a combination of organic material and Cd oxide. Electron backscatter diffraction (EBSD) determined that the Cd whiskers were single crystal with a preferential 1 ̅21 ̅0 growth direction.
