A non-dendritic microstructure normally forming the products made by the controlled diffusion solidification process (CDS) has been studied. Samples from Al-4.7 wt%Cu, Al-8 wt%Cu, and Al-4.7 wt%Zn were made via the CDS process by mixing pure aluminum into Al-Cu and Al-Zn binary alloys at a different mass ratio. ANSYS software was employed to predict the distribution of the mixed alloys during the mixing step. The simulation results show that the mixed alloys breakdown to different size pockets. The higher mass pockets fall into the bottom sample after the mixing step resulting in effect the microstructure forming in the entire sample. The experimental results indicate that globular mixed with rosette and dendritic morphologies form the entire microstructure, although all the morphologies were exposed to the same thermal environment during growth. The results show that the globular morphologies form in the undercooled alloy that have a higher liquidus temperature, while the dendritic morphologies form from the alloy that has a lower liquidus temperature, which is heated during the mixing.

已经研究了通常形成通过受控扩散固化工艺（CDS）制成的产品的非树状微结构。通过将纯铝以不同的质量比混合到Al-Cu和Al-Zn二元合金中，通过CDS工艺制备了Al-4.7 wt％Cu，Al-8 wt％Cu和Al-4.7 wt％Zn的样品。ANSYS软件用于预测混合步骤中混合合金的分布。仿真结果表明，混合合金分解为不同尺寸的凹穴。在混合步骤之后，较高质量的凹穴落入底部样品中，从而导致在整个样品中形成微观结构。实验结果表明，尽管在生长过程中所有形态都暴露于相同的热环境中，但球形与玫瑰花结和树突状形态混合形成了整个微观结构。
