Revisión de las características de gradientes microestructurales en compuestos metálicos de aluminio funcionalmente graduado y su mecanismo de formación.

Abstract

Functionally Graded Materials, FGMs are a type of advanced composite materials featuring a microstructural gradient, designed and manufactured by various methods, and possessing a gradually changing structure in volume. The objective of this work is to carry out a review about this type of materials formed by metallic aluminum alloys as a matrix and whose formation mechanism is by centrifugal casting, considering the manufacture by ex situ or solid particles and in situ. Through the analysis of related information, this paper review is developed, which deals with the influence of microstructure on the behavior of aluminum-based FGMs and determines the importance of computational modeling for its design and the feasibility of obtaining it.
