Study of growth mechanism of TiC cluster in ferrite via molecular dynamics simulation
YA Lv and P Hodgson and LX Kong and WM Gao, MATERIALS LETTERS, 159, 389-391 (2015).
Atomistic simulations were used to investigate the evolution process of titanium carbide clusters to mature precipitates in ferrite. The typical kinetic of carbide cluster growth was studied in detail through analyzing the atomic interactions of a carbide cluster with scattered carbon atoms. The driving force required for cluster growth was calculated along with the atomic diffusivity in the iron matrix, exploring the change in response as two main growth steps. The growth kinetic improved the understanding of precipitate evolution at the atomic level. (C) 2015 Elsevier B.V. All rights reserved.
