Cast metal matrix composites
TLDR
In this paper, the manufacturing processes for metal matrix composites, in particular those based upon liquid metal technology, e.g., squeeze casting and spray forming, are described. And an analysis of how matrix alloy selection may influence tensile and fracture behaviour of short fibre and particle reinforced composites is attempted.Abstract:
Metal matrix composites have been available in certain forms for at least two decades, e.g. boron fibre reinforced aluminium and various dispersed phase alloys and cermets. Recently, a range of alumina and silicon carbide fibres, whiskers, and particles with diameters <20 μm have become available. The possibilities of incorporating these materials into metals to improve stiffness, wear resistance, and elevated temperature strength without incurring weight penalties have attracted the attention of design engineers in the aerospace and automobile industries. The aim of the present paper is to outline the manufacturing processes for such composites, in particular those based upon liquid metal technology, e.g. squeeze casting and spray forming. Some of the mechanical and physical properties which have been determined for these materials are described. An analysis of how matrix alloy selection may influence tensile and fracture behaviour of short fibre and particle reinforced composites is attempted.MS...read more

Experimental investigation on mechanical behaviour, modelling and optimization of wear parameters of B4C and graphite reinforced aluminium hybrid composites
TL;DR: In this article, the worn surfaces of hybrid composites and base alloys were studied through SEM and EDS systems and some useful conclusions were made by using a pin-on-disc apparatus with various input parameters like applied load (10, 20, and 30 n), sliding speed (0.6, 0.8, and 1.0 n), and sliding distance (1000, 1500, and 2000 m).

The Determination of the Elastic Field of an Ellipsoidal Inclusion, and Related Problems
TL;DR: In this paper, it is shown that to answer several questions of physical or engineering interest, it is necessary to know only the relatively simple elastic field inside the ellipsoid.

Analysis of stress-strain, fracture, and ductility behavior of aluminum matrix composites containing discontinuous silicon carbide reinforcement
TL;DR: In this paper, the elastic modulus of aluminum matrix composites was found to be isotropic to be independent of type of reinforcement, and to be controlled solely by the volume percentage of SiC reinforcement present.

The elastic modulus of aluminium-lithium alloys
B. Noble,S.J. Harris,K. Dinsdale +2 more
TL;DR: In this paper, the Young's modulus of the Al3 Li and AlLi intermetallic phases are estimated to be 96 GPa and 105 GPa respectively, the major contribution to this increased modulus arises from lithium in solid solution.

The interface region in squeeze-infiltrated composites containing δ-alumina fibre in an aluminium matrix
TL;DR: In this paper, the authors examined the nature of interfaces formed between fine, δ-alumina fibres and aluminium-based matrices and concluded that any distinct chemical reaction product formed at the interface between fibre and matrix must be limited in extent to the atomic monolayer level.
