7.1   Introduction

Various characteristics of material are governed by numerous factors such as size, shape, circulation of solid particles throughout the material, solid fraction, shear rate, and viscosity of the material. During solidification, the conventionally cast alloys comprise dendritic morphology. The dendritic ...
