| Abstract: | A new type of dual phase steels was developed not containing Cr and Ni but Mn and Si. The steels show high strength as well as comprehensive plasticity because of strain induced phase transformation and transformation induced plasticity (TRIP) happened in the retained austenite in the steels. The mechanism of TRIP in plain carbon steel was discussed. The results show that the properties of this sort of TRIP steels containing Mn enhance with Si on condition that the amount of Si is less than two percent. |
