According to the Fe-P phase diagram, solubility of phosphorus in α-Fe at 1050°C is known be 2.8 wt%. This value extremely large compared with amount found commercial steel. Therefore, it has been supposed that steel might dissolve matrix, and any phosphide phases such as phosphide-inclusions or phosphide-precipitations not present all.However, confirmed research α γ-iron remarkably decreased by alloying forming elements. From this experiment should concluded are steels containing strong...
