摘要：
The generation of a {112}Sigma 3 grain boundary (GB) was observed in situ from the decomposition of a Sigma 9 GB during directional solidification of multicrystalline Si. A faceted groove formed at the junction of the solid/melt interface and the {112}Sigma 3 GB. This mechanism is different from that for the growth of (111)Sigma 3 GBs, for which no groove formed at the interface. If the growth rates for the adjacent facets of the groove are the same, the GB can grow in a straight manner along the (112) plane. The present results suggest that kinetics can give rise to high-energy GBs during solidification. (C) 2019 Acta Materialia Inc Published by Elsevier Ltd. All rights reserved.
