Study on the Second Phase Particles Precipitation Behavior during Deformation and Cooling of T700

Abstract:

In this paper, the precipitation behavior of T700 deformation and cooling process was studied by thermal simulation experiments and scanning electron microscopy. Results show that there are two kinds of carbide precipitates, precipitates needle is epsilon carbide precipitation in bainite, and is precipitated in the quenching process, circular granular precipitates during deformation due to strain induced precipitation. When the holding time is short, amount and size of precipitates are same as precipitation in the deformation. As the holding time longer, the number of precipitates in micro alloyed increase gradually, but very little change in size.
