Abstract

The microstructures and mechanical properties of a warm-forged and annealed Fe-18Mn-0.6C-1.5Al TWIP steel were studied. The high dislocation density was evolved by warm forging and the ultrafine grains were developed by subsequent annealing. The dislocation strengthening and the grain refinement result in increased yield strength ranging from 500 to 1000 MPa and the product of ultimate tensile strength by total elongation as high as 70,000 MPa pct.
