TL;DR: In this article, important techniques to process metal matrix composites are described, then the interface region and its characteristics, properties of different metal matrix composite composites, and finally, the authors summarize different applications of metal matrices composites.
Abstract: Metal matrix composites consist of a metal or an alloy as the continuous matrix and a reinforcement that can be particle, short fiber or whisker, or continuous fiber. In this chapter, we first describe important techniques to process metal matrix composites, then we describe the interface region and its characteristics, properties of different metal matrix composites, and finally, we summarize different applications of metal matrix composites.

TL;DR: In this article, a method of reshaping high strength fiber reinforced metal composite sheets is disclosed, which typically comprise unidirectionally oriented boron fibers in an aluminum matrix are metallurgically bonded to a pair of thin ductile metal face sheets.
Abstract: A method of reshaping high strength fiber reinforced metal composite sheets is disclosed. The sheets, which typically comprise unidirectionally oriented boron fibers in an aluminum matrix are metallurgically bonded to a pair of thin ductile metal face sheets. The resulting composite is then reshaped as desired by bending the composite along lines parallel to the fiber direction. Finally, the face sheets are removed, such as by acid etching, except in those areas in which it is desired to retain portions of the overlayer. Among other advantages, this technique permits much sharper radius bends by much simpler techniques that those previously used with such composite materials.

TL;DR: In this article, a phenomenological model is developed to evaluate the in situ plastic stress-strain properties of a metallic matrix containing fibres, from a study of the properties of the composite.
Abstract: In a fibre/metal matrix composite the mechanical properties of the matrix itself are changed by the presence of the reinforcing fibres. This changed behaviour of the metal is referred to asin situ behaviour, and a phenomenological model is developed to evaluate thein situ plastic stress-strain properties of a metallic matrix containing fibres, from a study of the properties of the composite. The model is based upon the idealised behaviour of the two components of the system. The application of the model to B/Al alloy composites shows that the plastic stress-strain behaviour of the matrix containing fibres varies strongly with the fibre volume content, and also that the matrixin situ cyclic stress-strain behaviour can be approximately described by a power law of the type: where the strength coefficient and the exponent increase with the fibre volume fraction. It also predicts that in the steady state fatigue behaviour of the composites, the fraction of load amplitude carried by the fibres decreases with increasing applied stress amplitude, and is also dependent on the fibre volume fraction. The effect of the applied stress on the damping capacity is established through expressions derived from the basic ideas involved in the model.
