説明
For the purpose of improving the impact properties of ferrite-pearlitic microalloyed steels through the refinement of structure, the steels with finely dispersed sulfides were produced by P/M process. In these steels, average manganese sulfide size was one-tenth of that in conventional steels (I/M steels) and the number of inclusions was increased about two digits. The ferrite-pearlite grain size was decreased by these inclusions. Although the impact values of the steels were increased by refinement of ferrite-pearlitic structure, they were decreased by the increase of the number of inclusions. Consequently, the impact value of the steels were not improved in comparison with conventional steels.<BR>Therefore, it is necessary to decrease the number of sulfides by controlling the sulfides slightly larger than those in the P/M steels. In this case, it is expected that the ferrite-pearlite grain size will become finer by the increase of intragranular ferrite in spite of increasing the prior austenite grain size.
