中文摘要：

研究了700~850℃等温时效对节约型双相不锈钢LDX 2101析出行为的影响。研究结果表明经等温时效处理,颗粒状析出物主要在奥氏体和铁素体相界处形核长大,从而恶化材料的冲击韧性。700℃是影响该材料冲击韧性最敏感脆化温度。在700℃等温时效处理120 min后,冲击韧性值降低到33 J,仅为固溶处理后冲击韧性值的31%。经过TEM观察分析,颗粒状析出物主要是Cr2N型氮化物以及少量Cr23C6型碳化物。

英文摘要：

Effect of isothermal aging on precipitation behavior of lean duplex stainless steel 2101 was studied.The results show that particle precipitates nucleate and grow at δ/γ interface which deteriorate impact energy during isothermal ageing.700℃ is the most sensitive embitterment temperature.After aged at 700℃ for 120min,the impact energy decreases to 33J,which is only 31% of the as-annealed sample.Based on TEM analysis,the particle precipitates are mainly Cr2N-type nitrides and a little of Cr23C6-type carbides.
