The research trends of steel composition,process and mechanical properties of nano phase ferrite were introduced.The influence of composition,finishing rolling temperature,cooling rate,coiling temperature and isothermal time of different Ti systems,Ti-Mo systems and Ti-Nb systems on the behaviors and mechanical properties of structure and nano particles in steel were analyzed.The observation and research trends of interphase precipitation behaviors of nano particles in ferritic steel were analyzed.Ledge mechanism,solute drag-depletion mechanism,and super-ledge mechanism of interphase precipitation behavior of nano particles were compared and analyzed,and the advantages and disadvantages of the three models were analyzed.Finally,it is proposed that the design of highly ordered composite precipitated nanoparticles at nanoscale is a new way to develop ultra-high performance and stable nanostructured engineering steel.
