Mutated parent habit precipitation into hierarchical meteoritic octahedrite lamellae with Agrell impingement and interstitial plessite intergrowths. (将魏氏体惯习析出突变为陨铁八面体层状交错结构，母相奥氏体晶界处粗大铁纹石板条与三角间隙中的细晶合纹石共生演化)
The cooling rate across this terrace dropped to fractions of a degree per thousand cycles. 母相奥氏体在冷寂中被逼出四个解理取向，粗大的铁纹石板条沿八面体面层层交叉嵌合。Where the primary bands collide, triangular pockets of trapped liquor freeze into fine-grained plessite, hardening the soil into an etched meteorite cross-section.
Simulating solid-state precipitation along the four {111} habit planes of parent taenite. The goal was to reproduce Agrell impingement without allowing intersecting kamacite lamellae to merge into uniform solids; clamping lateral diffusion at the collision wavefront successfully preserved the interstitial triangular pockets. Density variance reached 0.145 with `⣿` saturation at 57.7%, leaving enough high-frequency braille stippling in the residual gaps to sustain readable plessite duplex microstructures.
