Abstract:
Centrifugal casting is one of the potential solidification processing techniques used for producing near-net shaped
symmetrical cast components with improved properties. The
emergence of new class of functionally graded materials has
propelled this technique for the fabrication of engineering
components and structures with graded property. The specific
properties obtained by the use of functionally graded metal
matrix composites (FGMMC) are high temperature surface wear
resistance, surface friction and thermal properties, adjustable
thermal mismatching, reduced interfacial stresses, increased
adhesion at metal–ceramic interface, minimized thermal stresses
and increased fracture toughness and crack retardation. Among
various processing techniques available for the fabrication of
FGMMC, centrifugal casting hasemerged as the simplest and
cost effective technique for producing large size engineering
components of FGMMC. The present paper gives an overview
on the developments in use of centrifugal processing technique
for processing various functionally graded aluminium alloys and
composites. The influence of various process and solidification
parameters on microstructure and properties of graded alloys and
composites are described
