| 摘 要： | 不锈钢可通过压制与烧结水雾化粉末来制取.粉冶品级的不锈钢有铁素体、奥氏体、马氏体、两相(铁素体+奥氏体)、双相(铁素体+马氏体)以及沉淀硬化(马氏体)等不锈钢.开发双相粉冶不锈钢反映了对较高强度、较高延性与韧性的需求在增长.在本研究中,开发出一种新的低成本粉冶不锈钢,它将双相(铁素体+马氏体)显微结构与沉淀硬化的优点结合在一起.它与其他沉淀硬化合金不同,尽管这种不锈钢在时效后强度与韧性有所提高,但延性与冲击韧度的提高更大.借助组成与显微结构评估了新合金的力学性能. |

| Abstract: | Stainless steels can now be fabricated by the pressing and sintering of water atomized powder.PM grades embrace:ferritic,austenitic,martensitic,duplex(ferritic+austenitic),dual-phase(ferritic+martensitic),and precipitation hardening(martensitic).Development of dual-phase PM stainless steels reflects the growing need for higher strength,coupled with ductility and toughness.In the present study,a new low-cost PM stainless steel has been developed which combines the advantages of a dual-phase(ferrite+martensit... |
