文摘
- •
Growth models for grain boundary and intragranular Widmanstatten α were proposed.
- •
Clustered lamellar αWGB grows via adjacent lamellae merging and subsequent coarsening.
- •
Holes in thick lamellae expand and further fracture result in forked αWI.
- •
Merger of residual thick αWI with thin tertiary parallel αWI results in double forked αWI.
