In-situ Measurement of Solute Profile during Solidification of Metallic Alloys(<Special Issue>Square-shaped Si Crystals for Solar Cell use)

Abstract

The third generation synchrotron radiation facilities allow us to perform time-resolve and in-situ observation of solidification for metallic alloys. The quantitative measurement of X-ray absorption coefficient intransmission images gives two-dimensional solute concentration profile. The solute profile will be helpful for verifying and validating solidification models. This paper presents preliminary results of solute profile around dendrites in Fe-Si alloys.
