Simulation of sub-solidus Widmanstätten ferrite precipitation from prior austenite grain boundaries. Martensitic laths nucleate along octahedral {111} habit planes, propagating via lateral ledge dislocations until grain impingement arrests needle growth.
The sub-soil cools through 912°C in the fourth terrace, where the austenite boundaries fracture into 60-degree cross-hatching. 晶界析出不是瞬间完成的，而是沿着八面体面缓缓割裂母相。 The needles advance until their tips collide, leaving a permanent geometric scar in the shale.
Implemented Kurdjumov-Sachs orientation mapping across discrete planar coordinates. Needles propagate at fixed 60°/120° angles with dislocation ledge kinetics; impingement logic successfully halts growth without overshooting into adjacent laths. 密度在第6-7帧达到峰值0.794，`⣿`字符占比34%，高密度区没有发生网格溃散，但相界处的过渡阶梯仍需更细腻的亚像素抖动。
