T
he 304 and 316L stainless steels and 1020 and 1045
carbon steels with nano/micro-crystalline structure were
prepared by an aluminothermic reaction casting method.
The microstructural evolution of the stainless steel after
annealed with different time and temperature, rolled with
different thickness reduction and temperature, first cogged
and followed rolled with different thickness reduction and
temperature were studied. The microstructural evolution
of the carbon steel after annealed with different time and
temperature, rolled with different thickness reduction at
600°C. By analysis the grain size of nanocrystalline austenite,
submicrocrystalline austenite and ferrite, and their volume
fraction in stainless steels; the volume fraction and lamellar
spacing of the pearlite, the shape of the cementite in pearlite
in carbon steels. We raised themechanisms of microstructure
evolution.
