A Review on Corrosion Behavior of Nickel Matrix Composites
Nickel in elemental form or alloyed with other metals or materials has made significant contribution to our present day society. Nickel and nickel alloys are the class of advanced material that are are identified as candidate materials for marine applications and vitally important to aerospace, automotive industries because of their ability to withstand a wide variety of severe operating condit...
متن کاملMatrix cracking of fiber-reinforced ceramic composites in shear
The mechanics of cracking in fiber-reinforced ceramic matrix composites (CMCs) under general loadings remains incomplete. The present paper addresses one outstanding aspect of this problem: the development of matrix cracks in unidirectional plies under shear loading. To this end, we develop a model based on potential energy differences upstream and downstream of a fully bridged steady-state mat...
متن کاملWear of ceramic particle-reinforced metal-matrix composites
Wear experiments have shown that when the applied normal stress exceeds a critical value, a transition occurs from the regime of mild wear to that of adhesive wear. As a result, the wear rate of particle-reinforced aluminium composites increases by a hundred-fold. Based on dislocation and delamination theories, a criterion is proposed for determining the critical transition load, and a quantita...
متن کاملCeramic matrix composites containing carbon nanotubes: The story so far
Due to the remarkable physical and mechanical properties of individual, perfect carbon nanotubes (CNTs), they are considered to be one of the most promising new reinforcements for structural composites. Their impressive electrical and thermal properties also suggest opportunities for multifunctional applications. In the context of inorganic matrix composites, researchers have particularly focus...
متن کاملNondestructive Damage Evaluation in Ceramic Matrix Composites for Aerospace Applications
Infrared thermography (IRT) and acoustic emission (AE) are the two major nondestructive methodologies for evaluating damage in ceramic matrix composites (CMCs) for aerospace applications. The two techniques are applied herein to assess and monitor damage formation and evolution in a SiC-fiber reinforced CMC loaded under cyclic and fatigue loading. The paper explains how IRT and AE can be used f...
