Effect of Molybdenum on Creep Properties of a Ferritic 18Cr-Nb-Ti Steel for Catalytic Converters
JOM - Tập 33 - Trang 19-24 - 2014
The effect of 1 and 2% molybdenum additions on the creep rate and rupture strength of a Nb-Ti stabilized 18% Cr steel at 870°C (1600°F) was investigated. The steels were tested in three conditions: as-recrystallized, prestrained 5%, and aged at 760°C (1400°F) for 200 hours. Molybdenum improves the rupture strength and reduces the creep rate of the steel in all three conditions. Molybdenum is espec......
Refractory Corrosion Mechanisms in a Novel High Carbon Ferromanganese Production Furnace
JOM - Tập 68 - Trang 3029-3039 - 2016
The present paper presents the refractory design for a novel HCFeMn smelting furnace that, other than standard submerged arc furnaces, allows the processing of fine ores. A combination of basic and non-basic materials, comprising bricks, castables and ramming was chosen, under consideration of the unique furnace design and process conditions. Post-mortem investigations on refractory samples from ......
Modeling and Simulation of Nanoindentation
JOM - Tập 69 - Trang 2256-2263 - 2017
Nanoindentation is a hardness test method applied to small volumes of material which can provide some unique effects and spark many related research activities. To fully understand the phenomena observed during nanoindentation tests, modeling and simulation methods have been developed to predict the mechanical response of materials during nanoindentation. However, challenges remain with those comp......
The transient plastic phase processing of ceramic-ceramic composites
JOM - Tập 47 - Trang 52-55 - 1995
A recently developed processing technique called transient plastic-phase processing (TPPP) is capable of the in-situ net-shape manufacturing of complexly shaped, fully dense, ultrarefractory composites at much lower (homologous) temperatures than those currently used. The viability of this technique as well as its advantages over the traditional processing routes has been demonstrated for the Ti-B......
