| description | The invention relates to the technical field of high-strength steel, in particular to high-strength TRIP-TWIP steel and a preparation method thereof. According to the specific technical scheme, the preparation method of the high-strength TRIP-TWIP steel comprises the steps that raw materials of the TRIP-TWIP steel are subjected to smelting and ingot casting and then forged into a plate blank, the plate blank is subjected to hot rolling treatment at the initial rolling temperature of 1050-1150 DEG C and the final rolling temperature of 900-950 DEG C and cooled to the room temperature in an air cooling mode, a hot-rolled plate is obtained, and after the hot-rolled plate is subjected to cold rolling and annealing treatment, the high-strength TRIP-TWIP steel is obtained. And obtaining the cold-rolled annealed plate. The TRIP-TWIP steel prepared through the method has the mechanical property characteristic of ultrahigh strength, the technology is integrated, twin crystals are introduced into traditional TRIP steel |
