| 摘 要： | 研究了粉末烧结双相不锈钢及其时效后的相结构和强韧性。结果表明,在316L粉末中添加4%(wt)St,用粉末烧结法可以获得奥氏体加18%(Vol)铁素体的双相不锈钢。该双相不锈钢在800℃时效时,沿奥氏体和铁素体界面析出条状σ相,使双相不锈钢的硬度增加,塑性下降。

| Abstract: | The phase structure and high toughness of powder sintered biphase stainless steel and after its ageing have been studied. Results have shown that biphase stainless steel with 18vol% ferrite and austenite can be obtained by adding 4 wt% Si in 316L powder using powder sintering process. After ageing at 800℃, a strip-shaped phase was precipitated along the interface between austenite and ferrite of the biphase stainless steel and that made the hardness of biphase stainless steel increase and plasticity decrease. |
