According to the theory of peritectic metastable phase diagram, because of the nonequibrium effect of interface, the equilibrium peritectic phase diagram would transform to metastable eutectic phase diagram during directional solidification, so the lamellar structure formed.
应用Zn-Cu包晶合金亚稳相图分析认为,在定向凝固条件下,由于界面非平衡效应的影响,平衡的包晶相图将发生向亚稳共晶相图的转变,形成两相层片状生长的组织。
