Creep Behavior and Microstructures of Nb-26Ti-48Al Alloy and Composite
Published online by Cambridge University Press: 15 February 2011
Abstract
The creep behavior of Nb-26Ti-48Al alloy and its composite were investigated. After creep testing, precipitates were observed in the composite and mobile dislocations were found to be pinned by these precipitates. The combined effects of the reinforcements and the pinned dislocations were responsible for a reduced creep rate of the composite. The possible creep mechanisms were discussed based on the stress exponent and the activation energy of creep.
