Application of Solidification Theory to Rapid Solidification Processing

Abstract

The objective of this work is to develop guidelines based on kinetic and thermodynamic solidification theory for prediction and control of rapid solidification processes. In particular, segregation effects and rules governing the formation of equilibrium and non-equilibrium phases, including metallic glasses, will be investigated. Areas where significant improvements in alloy properties can be produced by rapid solidification will be emphasized. Significant accomplishments during the period were achieved in the following areas: Extended Solid Solubilities -- for Production of Alloys with New Compositions and Phases; Interface Stability -- for Production of More Homogeneous Alloys; Interface Kinetics -- for Production of Alloys with Finer Segregation; Prevention of Cracking Caused by Residual Stress -- for Production of Alloys with Improved Surface Structures.
