An In Situ Observation of Slip Deformation in a Compressed Ti-Mo-Al Single Crystal

Abstract:

The stress-induced martensitic transformation and slip deformation behavior were investigated by the compression test with an in-situ observation in a Ti-6Mo-10Al (mol %) alloy single crystal. Owing to the stress-induced martensitic transformation from the parent β phase to the α′′ martensite phase, the single crystal of α′′ martensite without internal twinnings was successfully obtained at room temperature. By further compression, the slip deformation occurred in the single crystal of α′′ martensite. The operated slip system in the α′′ martensite was analyzed by the two face trace analyses, and the slip direction was determined to be []_o.
