Abstract
- The deformation behavior of duplex stainless steel 2205 is investigated by the method of high-temperature tensile and compressive tests using Gleeble 1500. The results of the tensile tests show that the tensile strength gradually decreases with increase in the deformation temperature; in the temperature range from 1020 to 1260°C the reduction of area is more than 60%. The incoordinate deformation of the two-phase tested steel in the range of 1020 – 1080°C leaves 1100 – 1200°C a suitable range for hot deformation. The results of compressive tests at the temperatures from 1100 to 1200°C show that the flow curve has typical features of dynamic recrystallization; with increase of the deformation temperature or decrease of the deformation rate, the peak stress and strain decrease separately; from this the Zener–Hollomon parameter is determined, which reflects the flow property of the tested steel, and an equation is proposed to describe the hot deformation.
