After exploring the influence of stress,cold-rolling reduction and cooling rate on transforma- tion induced strain,the transformation induced superplasticity forming technique of the 18Ni maraging steel(2450 MPa)was developed.Through 14 times γα′ cyclic transformation,the limited elongation of 320% can be obtained in 60% cold-rolled specimen.TEM observation revealed that the morphology of stress induced martensite is massive.
