Fabrication of Fe-Cr-Al Oxide Dispersion Strengthened PM2000 alloy using Selective Laser Melting**
The expansion in application of the selective laser melting (SLM) process for fabrication of new alloy materials continues. However, to date, there has been no investigation of the effect of this process on the final microstructure of ‘melt sensitive’ powder alloys such as mechanically alloyed oxide dispersion strengthened (ODS) FeCrAl. In this study commercial PM2000 powder, a ferritic ODS all...
متن کاملElectrochemical and Tribological Behaviour of Oxide Dispersion Strengthened Duplex Stainless Steel in Mine Water Environment
Abstract This work investigated the electrochemical and aqueous tribological behavior of hot pressed 2205 duplex stainless steel (DSS). DSS sintered composites of different volume percent (% vol) of partially stabilized zirconia (PSZ) was developed using powder metallurgy (PM) technique. Electrochemical behaviour was studied at room temperature, using open circuit potential and potentiody...
متن کاملChemical Synthesis and Oxide Dispersion Properties of Strengthened Tungsten via Spark Plasma Sintering
Highly uniform oxide dispersion-strengthened materials W-1 wt % Nd₂O₃ and W-1 wt % CeO₂ were successfully fabricated via a novel wet chemical method followed by hydrogen reduction. The powders were consolidated by spark plasma sintering at 1700 °C to suppress grain growth. The samples were characterized by performing field emission scanning electron microscopy and transmission electron microsco...
متن کاملInfluence of Texture on Impact Toughness of Ferritic Fe-20Cr-5Al Oxide Dispersion Strengthened Steel
Fe-based oxide dispersion strengthened (ODS) steels are oriented to applications where high operating temperatures and good corrosion resistance is paramount. However, their use is compromised by their fracture toughness, which is lower than other competing ferritic-martenstic steels. In addition, the route required in manufacturing these alloys generates texture in the material, which induces ...
متن کاملNanoscale lamellae in an oxide dispersion strengthened steel processed by dynamic plastic deformation
The microstructure of an oxide dispersion strengthened ferritic PM2000 steel with a strong initial 〈100〉 texture has been investigated after compression by dynamic plastic deformation (DPD) at room temperature to a strain of 2.1. Measurements using electron backscatter diffraction and transmission electron microscopy indicate that DPD along the 〈100〉 direction results in a lamellar-type microst...
