Metal Matrix Composites: Thermomechanical Behavior discusses metal matrix composites, elaborating on that consists of two phases—fiber as reinforcement and metal as matrix. This book focuses on polymer matrix composites, including topics in metal matrix composites ranging from processing to fracture mechanics. The three basic types of composite materials—dispersion-strengthened, particle-reinforced, and fiber (whisker)-reinforced, are also described in detail. Dispersion-strengthened is characterized by a microstructure consisting of an elemental matrix within which fine particles are uniformly dispersed, while particle-reinforced is indicated by dispersed particles of greater than 1.0 μm diameter with a volume fraction of 5 to 40%. Fiber (whisker)-reinforced provides a distinguishing microstructural feature of fiber-reinforced materials, such as that the reinforcing fiber has one long dimension, while the reinforcing particles of the other two types do not. This publication serves as a reference data book to students and researchers aiming to acquire knowledge of the thermomechanical behavior of metal matrix composites.

An investigation was undertaken to evaluate the constitutive response and in-elastic deformation characteristics in titanium-based metal matrix composites (MMC) with two types of ceramic fibers, namely, SCS-6 and Sigma. The titanium matrix was Beta 21S, currently named TIMETAL-21S. Monotonic tests were conducted at room temperature (RT) and between 483 and 815°C. The inelastic deformation in the [0]8 lamina under compression was controlled primarily by matrix plasticity, although some evidence of fiber-matrix debonding was observed. The inelastic deformation mechanisms under compression in [90]8 lamina were primarily due to radial fiber cracking from the core for the SCS-6 fiber and fiber-matrix debonding. However, for the Sigma fiber, radial cracking was absent. The effect of temperature on degradation of mechanical properties such as modulus and yield strength for the composites with two different fibers were compared.

The nonlinear anisotropic mechanical behavior of an aluminum alloy metal matrix composite reinforced with continuous alumina fibers was determined experimentally. The mechanical behavior of the composite were modeled by assuming that the composite has a periodical microstructure. The resulting unit cell problem was solved with the finite element method. Excellent agreement was found between theoretically predicted and measured stress-strain responses for various tensile and shear loadings. The stress-strain responses for transverse and inplane shear were found to be identical and this will provide a simplification of the constitutive equations for the composite. The composite has a very low ductility in transverse tension and a limited ductility in transverse shear that was correlated to high hydrostatic stresses that develop in the matrix. The shape of the initial yield surface was calculated and good agreement was found between the calculated shape and the experimentally determined shape. Jansson, S.
