采用热压缩和热拉伸试验方法,对节镍型双相不锈钢00Cr21Mn5Ni1N的高温变形抗力、高温塑性及高温变形时奥氏体相的数量进行了研究。结果表明,00Cr21Mn5Ni1N双相不锈钢在950~1 200℃之间变形时,具有良好的热加工性能,钢中奥氏体相量可以控制在适合热加工的范围。
The hot deformation and hot tensile test methods were used to study the high temperature deformation resistance, high temperature ductility and the number of austenite phases in the high temperature deformation of 00Cr21Mn5Ni1N nickel-based duplex stainless steel. The results show that the 00Cr21Mn5Ni1N duplex stainless steel has good hot workability when deformed from 950 ℃ to 1200 ℃, and the austenite phase in the steel can be controlled in the range suitable for hot working.
