Coal gasification combined cycle power plants promise lower emissions and higher efficiencies than conventional pulverized coal power plants. Process economics favor compact, high pressure, slagging gasifiers, usually of the entrained type, for most coals. The high raw gas temperature in such plants prevent the use of uncooled metals in contact with the gas. Direct metal/gas contact usually occ...
Influence 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 ...
