Abstract

Abstract A surface cladding is required to maintain structural integrity for tungsten-fiber-reinforced superalloys exposed to air at high temperatures. Under thermomechanical loading, surface crenulations appear in the cladding as a result of extensive plastic flow caused by thermal expansion and modulus mismatch with the composite. These crenulations eventually lead to transverse cracks which show stable propagation. In addition, transverse swelling occurred in the hot section of the specimen, reflective of extensive plastic flow and void formation in the matrix.
