Comprehensive Analysis for Microstructure Evolution in Welding
Unidirectional solidification for low-carbon steel weld metal was characterized by using Time-Resolved X-Ray Diffraction (TRXRD) system. Solid-state phase transformation was also insitu observed in reciprocal lattice space. It was shown that TRXRD analysis had a potential as a comprehensive characterization technique for solidification and phase transformation process in welding. It made for the growth behavior of dendrites in unidirectional solidification and α γ δ − − phase transformation in steel weld metal to be characterized.
