Numerical simulation of macrostructure formation in centrifugal casting of particle reinforced metal matrix composites. Part 1: model description

Abstract

This paper discusses the processing, modelling and macrostructure management of centrifugally cast particle reinforced metal matrix composites (MMCs). Centrifugal casting is a widely applied method for production of graded MMCs. A three-dimensional comprehensive mathematical model coupling particle movement and thermal conduction in the casting/mould system is developed. A formula for pressure in liquid metal during the centrifuge process is derived. The influence of Coriolis force on particle movement is discussed in detail.
