A coarse constituent resulting from the coalescence of platelets of bainite has recently been
discovered in high-strength steel weld metals. The three-dimensional shape of coalesced
bainite has been investigated by serial sectioning using a focused ion beam milling facility
supplemented with observations made using field emission gun scanning electron
microscopy and light optical microscopy. A compilation of the sections into a threedimensional
model revealed the shape of the coalesced bainite grain to be lath-like with a
length in excess of 20 μm.
