ÕæÀíµÄ³öÏÖ²»ÔÚÓÚÔç»òÍí£¡Â¥Ö÷ǧÍò±ð´í¹ýßÏ![]() Due to the reduction of the interfacial energy, from which the driving force of the grain evolution in monophase multicrystal system is originated, and the particle from the second phase locating on the boundary surface enable the lowering of interfacial energy, the area of the grain boundary and the interfacial energy reduce to a minimumvalue when the round/sperical second-phase particle occupy the trimorphous intersection, whereas the bar-shaped/stick second-phase particle locate on the boundary surface with their orientation parallel to the boundary. It is in accordance with the tendency for the system to evolve. [ Last edited by noleg on 2010-6-11 at 21:37 ] |
