18cr9ni3cunbn奥氏体耐热钢中富cu相的早期析出行为
Keywords: 金属材料,奥氏体耐热钢,18cr9ni3cunbn,三维原子探针技术,富cu相,c曲线
Abstract:
？应用三维原子探针技术研究了600℃超超临界电站锅炉过热器/再热器用18cr9ni3cunbn奥氏体耐热钢中强化相富cu相的早期析出行为,并绘制出富cu相在18cr-9ni型奥氏体耐热钢中的c曲线。结果表明:在高温时效过程中富cu相无论在650℃还是在700℃均能较快地析出,其形成过程都是在短时间内先形成富cu偏聚区,随着时效时间的延长cu原子继续扩散到富cu偏聚区,其它原子如fe,cr,ni等则被排出富cu偏聚区而扩散到奥氏体基体中,最终形成富cu相。
