The simulated results show that for the small sample decreasing sample size or nucleation undercooling of peritectic phase tended to form island band structure. But to the big sample, the differences of the volume fraction of peritectic phase and the nucleation rate cause to form the discrete band, island band and coupled-growth ructures Key words:  peritectic alloy      directional solidification      phase-field model       Received:  21 September 2005      ZTFLH:  TG111   Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors SU Yanqing LI Xinzhong GUO Jingjie WU Shiping FU Hengzhi URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y2006/V42/I6/606 [1] Boettinger W J.
