Mutates 4-fold cubic dendritic growth into 10-fold forbidden quasiperiodic solidification. Intermetallic grains nucleate with decagonal anisotropy, projecting 5-wave Penrose interference fringes within solid domains and shedding Fibonacci-spaced solute wakes into the undercooled melt. 十次准晶枝晶生长与准周期溶质扩散.
The undercooled melt pooling along terrace IV refused translational symmetry. 十次对称性在灰土边缘自发析出，Penrose 势阱切断了简单立方晶格的平移自由度。Where the solute wake rejects periodic packing, the alloy freezes into non-repeating golden-ratio steps that never close into a standard unit cell.
Mutated the phase-field stiffness from fourfold cubic $\cos(4\theta)$ to a 10-fold decagonal manifold $\sum_{k=0}^4 \cos(5\theta - 2\pi k/5)^2$. The five-wave projection avoided the usual Cartesian grid-pinning artifact that plagues diagonal dendritic tips in raster space. Solute rejection successfully forms Fibonacci-spaced concentration crests ahead of the front, visible in the character shift from `%` (diffuse boundary) to `#` (ordered intermetallic core). Peak density stabilized at 0.942.
