摘要:

利用KKSO三维多相场模型, 在等层片宽度和厚度条件下, 研究了 CBr₄-C₂Cl₆共晶合金在不同初始层片间距条件下的三维形态演化过程、层－棒转变及三维层片间距调整机制. 研究表明, 对于亚共晶、共晶成分的CBr₄-C₂Cl₆合金, 不同的初始层片间距可能导致共晶形态发生层--棒转变, 且发生层--棒转变的趋势与初始层片间距的大小有关; 而过共晶成分的CBr₄-C₂Cl₆合金不会发生层－棒转变, 维持层片生长. 而且当无量纲初始层片间距在0.598-2.336之间变化时, 随着层片间距的增加, 其演化顺序为: 层片湮没后形成 1λO→T-xλO→1λO→2λO→分叉与形核→Z字型分叉→无序组织. 研究还表明,三维层片间距调整机制与二维层片间距调整机制类似, 基本机制为层片湮没和层片分叉. 当初始层片间距较小时, 发生层片湮没现象. 而当初始层片间距较大时, 层片发生分叉. 但由于多了第三方向的限制作用, 三维层片间距调整机制比二维复杂.

Abstract：

Using KKSO multi-phase field model, with equal lamellar width and thickness, three dimensional (3D) morphology evolution, lamellar-rod transition and the mechanism of adjustment of lamellar spacing of CBr₄-C₂Cl₆ alloys are investigated at different initial lamellar spacings. It's found that, as for the hypoeutectic and eutectic CBr₄-C₂Cl₆ alloy, different initial lamellar spacings may lead to lamellar-rod transition, which is related to the initial lamellar spacings. The CBr₄-C₂Cl₆ hypereutectic lamellar alloy can't transit to rod-like eutectic, with the increase of the dimensionless initial lamellar spacings Λ in the range of 0.598-2.336, the sequence of morphology evolution is: lamellar merges to form 1λO→T-xλO→1λO→2λO→lamellar branching→zigzag bifurcation $\rightarrow$ lamellar destabilizes to form the disordered pattern. The simulated results also showed that the mechanism of adjustment of lamellar spacing in 3D of the CBr₄-C₂Cl₆ hypereutectic alloy is similar to that in two dimensions (2D), which is lamellar annihilation and branching on the whole, the lamellar annihilation takes place with a smaller initial lamellar spacing while the lamellar branching takes place with a bigger initial lamellar spacing. The adjustment mechanism of the lamellar spacing in 3D is more complex than that in 2D because of the additional effect of the third dimension.

Key words： three dimensional multi-phase field eutectic morphology evolution lamellar-rod transition adjustment of lamellar spacing
