| Abstract: | Ultra-high strength steels (UHSS) are widely applied in the automobile industry by the excellent strength, ductility and toughness. The alloying modes and strengthening mechanism of ultra-high strength steels for automobile were introduced in detail. And the plasticizing effect of microstructure generated by the austenite and its phase transformation, and the regulation method of microstructure were elucidated in detail. |
| |
| Keywords: | ultra-high strength steel alloying transformation-induced plasticity twinning-induced plasticity retained austenite |
