Cg. De Andres et al., Improvement of mechanical properties in a forging microalloyed steel throughout the control of the anisothermal decomposition of austenite into acicular ferrite, REV METAL M, 37(2), 2001, pp. 240-244
The aim of this work is to study the anisothermal decomposition of austenit
e at two different austenisation conditions in a medium carbon microalloyed
steel. Ln this sense, continuous cooling transformation diagrams (CCT) hav
e bo:cn obtained for both austenisation conditions to determine the continu
ous cooling that allows the formation of a microstructure mainly formed of
acicular ferrite with the best mechanical properties. The knowledge of the
anisothermal decomposition of austenite in this steel has allowed to propos
e continuous cooling cycles for industrial aplication. That produce high vo
lume fraction of acicular ferrite.
