Characterization of microstructures, mechanical properties

Jan 31, 2011 · Two Fe-Al-Ti alloys with coherent Fe,Al (A2) + Fe 2 AlTi (L2 1) microstructures have been produced and the evolution of the microstructure with aging time has been studied by light optical and scanning electron microscopy and hardness measurements.The compressive flow strength, creep properties, brittle-to-ductile-transition temperatures (BDTT), and oxidation behavior of the alloys High-Temperature Oxidation Behavior of Fe-Si-Ce AlloysFigure 3 shows the kinetic curves of Fe-3.0Si-0Ce, Fe-3.0Si-0.5Ce and Fe-3.0Si-5.0Ce alloys when being oxidized at 1,173 and 1,273 K in pure oxygen, indicating that the addition of 0.5 mass% Ce noticebly decreases the oxidation mass gain of Fe-3.0Si alloys, while as the Ce content futher increases to 5.0 mass%, the mass gain increases slightly.

Oxidation behavior of a Ni-Fe support in SOFC anode

N2 - In this work, we investigated the long-term oxidation behavior of a Ni-Fe (1:1 weight ratio) support for solid oxide fuel cell (SOFC) applications. Ni-Fe supports were obtained through tape casting, high temperature sintering and pre-reducing in 97% H2/N2 (9/91)-3% H2O at 750 and 1000 °C, respectively. Reactive molecular dynamics study of the oxidation May 14, 2021 · Reactive dynamics simulations are performed to capture the effects of Cr addition on the oxidation behavior of Fe and FeCr alloy in supercritical water (SCW), by analyzing the evolution of Structural evolutions and oxidation behavior of Fe-doped Dec 15, 2019 · The calculated weight gain as a function of time was used to determine the oxidation behavior of SiFeOC ceramics and described by the following equations:(3) W = m 0 m 1 m 0 × 100 % Where W is the weigh change of SiFeOC ceramic, m 0 is the mass of the SiFeOC ceramic before oxidation test, and m 1 is the mass of the SiFeOC ceramic after oxidation test.

Oxidation Behavior of Fe-Al, Fe-Si and Fe-Al-Si Intermetallics

Results showed that the oxidation of Fe-Al-Si ternary alloys provides an oxide layer based on aluminum oxide with a low concentration of iron and silicon. Below this oxide layer, there is a layer of silicides formed as a result of depletion by aluminum, which forms a secondary oxidation protection.
