Abstract
Subject headings
Close
- Solid metal induced embrittlement (SMIE) occurs when a metal experiences tensilestress and is in contact with another metal with lower melting temperature. SMIE is believed tobe a combined action of surface self-diffusion of the embrittling species to the crack tip andadsorption of the embrittling species at the crack tip, which weakens the crack tip region. In thepresent study, both SMIE of the near alpha alloy Ti-8Al-1Mo-1V in contact with copper and itsinfluence by crystallographic orientation have been studied. U-bend specimens coated withcopper were heat treated at 480°C for 8 hours. One of the cracks was examined in detail usingelectron backscatter diffraction technique. A preferable crack path was found along high anglegrain boundaries with grains oriented close to [0001] in the crack direction; this indicates thatthere is a connection between the SMIE crack characteristics and the crystallographicorientation.
