摘要：
The morphological evolution of gamma-hydride precipitation and growth in a zirconium bi-crystal is simulated using a phase field kinetic model. The result shows the heterogeneous nucleation at the grain boundary. The likelihood of hydride growth across the grain boundary is discussed. (C) 2002 Acta Materialia Inc.
