外文摘要：On the basis of these preliminary studies， it can be concluded that: 1) In the case of IF steels it might be difficult to produce ultra-fine grained material commercially， due to the narrow temperature of the austenite + ferrite phase field。 2) A more promising path for stronger IF steels is the use of alloying to produce bainitic ferrite with high dislocation densities。 3) The binary alloying of B+Nb produces a mixture of quasi-polygonal and bainitic ferrite， with a modest increase in strength effect 4) The ternary alloying of B+Nb+Mo exhibits the largest increase strength， with a bainitic ferrite structure that can be produced by a variety of processing paths。
