Compared with cold forming,hot forming is more appropriate for the high-strength and low plasticity RAFM(reduced activation ferritic/martensitic)steels used in the fusion energy systems.It is important to realize the influence of processing parameters(as strain rate and deformation degree)on the microstructure of RAFM steels.The low carbon RAFM steel has been developed by our group,to improve the creep properties by means of increase of MX precipitates density.In order to optimize the processing parameters for hot forming of the low carbon RAFM steel,hot compressive tests were conducted at 1050 ℃ under the different strain rates(0.1,0.01,1 and 10 s-1)and deformation degrees(0%,20%,40%and 60%)by Gleeble-3500 thermo mechanical simulator.
