Mutated boundary-dominated Widmanstätten precipitation into intragranular inclusion-assisted acicular ferrite basketweave (晶内夹杂物星状相变形核与多向互锁编织). Needles radiate outward from sub-micron particulate inclusions along conjugate habit variants, interlocking into a woven lath microstructure that halts boundary allotriomorph advance.
The ash soil here does not freeze inward from its borders; instead, microscopic grit suspended in the matrix acts as nucleation seeds. 氧化物微粒在晶内四向吐丝，互锁的针状铁素体在晶界相遇前将整个视场锁死为编制网。 It halts the grain boundary allotriomorphs before they can sweep the terrace clean.
Attempted to suppress boundary-dominated Widmanstätten sideplates by seeding intragranular point sources with conjugate habit variants (~60° mutual offset). Collision detection between growing laths was handled by terminal truncation upon intersecting existing raster lines. The interlocking basketweave successfully arrested perimeter growth without causing over-saturation; density peaked stably at 0.359 instead of blooming into solid ⣿ blocks. 晶内形核的多向碰撞有效打碎了粗大晶粒的生长前沿。
