Abstract

Abstract: After the solution treatment and cold rolling deformation of 00Cr22Ni5Mo3N duplex stainless steel, its super plastic deformation test is made at 850～1000℃ for 5 minutes. The effect of deformation temperature on the superplasticity of 00Cr22Ni5Mo3N is studied. Its microstructure before deformation is observed, and the influence of sigma phase and microstructure changes on the superplasticity is researched. The reason why the deformation temperature affects the superplasticity of 00Cr22Ni5Mo3N is revealed. The results show that, when the deformation temperature changes, the microstructure and quantity of σ phase changes, and so does the superplasticity. After solution treatment at 1300℃, 85% of cold rolling deformation, and holding at 850～1000℃ for 5min, its microstructure is recrystallized, the uniform equiaxed grains become more and more with the increase in deformation temperature, and the number of sigma phase gets smaller. Meanwhile, the elongation of 00Cr22Ni5Mo3N duplex stainless steel increases from 480% to 1290%, and the peak stress decreases from 125MPa to 32MPa.

Key words: metallic material, duplex stainless steel, superplasticity, deformation temperature, σ phase, microstructure transformation
