Solidification phase and microstructure selection maps for Fe-Cr-Ni alloys

Abstract

Directional solidification and laser experiments have been performed in Fe-18.0%Cr-Ni alloys to evaluate the effects of alloy composition and growth velocity on microstructure and phase selection. Solidification microstructure selection maps are described by microstructure (dendrite/cell, plane front and eutectic) models and compared with experimental results. Theoretical predictions are in good agreement with experimental results. It demonstrates the potential of this approach to analyze the microstructure and phase formation.
