Study of crystallization and growth behavior of NbC on solidification process of SUS347H weld metal

Study of solidification microstructure on austenitic weld metal (6)

Abstract

Verification of the modified numerical motel to predict the solidification microstructure of weld metal which is taken into account for d/g phase and NbC eutectic growth was investigated with using in-situ observation experiment of solidification process of weld metal by synchrotron radiation. Crystallization and growth behaviors of NbC on SUS347H weld metal was investigated by the developed numerical model.
