SOLIDIFICATION OF PURE METAL TUSHAR ANEYRAO
Contents • Solidification of Metals • Nucleation and Grain Growth • Cooling Curves • Homogenous Nucleation • Heterogeneous Nucleation • Dendrites • Shrinkage
Why? • Knowledge of solidification leads to understanding of successful and defect free casting process. • Many important characteristics such as CRYSTAL SRUCTURE & ALLOY COMPOSTION at different parts of metal are decided in Solidification Process
Types of Crystal • Columnar Crystal • Dendritic Structure
