Determining interfacial thermal residual stress in SiC/Ti-15-3 composites

Interfacial residual stress in SCS-6/Ti-15-3 was determined using a novel technique of combining the electron moire method and the pushout test. The residual stress at the interface was released by pushing the fiber out. The residual strains were measured using the electron moire technique. A compressive residual stress of -473 MPa at the interface was measured. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
