摘要: Abstract Conventional transmission electron microscopy (TEM) and high-resolution (HREM) experiments have been carried out on thermally-aged binary Fe 1·30 wt% Cu ternary 1·28 1·43 wt.% Ni alloys to study the structure of small (7–15 nm) copper precipitates in α-Fe matrix. The show that a twinned 9R close-packed structure, rather than expected f.c.c. structure. It is believed this generated initially by martensitic transformation from metastable b.c.c. phase.
