Abstract

Abstract

High-temperature short-time tensile test of as-cast 2205 duplex stainless steel was performed and the variation of tensile strength and percentage reduction in area of the specimen at different temperatures was analyzed.The high-temperature microstructures and fracture morphologies were observed at 1 300 ℃,1 050 ℃,950 ℃ and 850 ℃.The test results showed that duplex stainless steel exhibited good plasticity at 1 150~1 350 ℃.Softening was inhibited due to high strain rate at 1 000~1 100 ℃,resulting in a brittleness temperature range Ⅱ present in the duplex stainless steel.In addition,crack propagated further due to loose and fine precipitation of the specimen.Presence of brittleness temperature range Ⅲ was the result of grain boundary embrittlement mainly caused by the nitride and carbonitride etc.precipitated at austenitic grain boundaries.
