Quantifying the Resistance to Dislocation Glide in Single Phase FeCrAl Alloy

SSRN Electronic Journal, 2019
Abstract The resistance to dislocation glide associated with slip systems {110} and {112} in single phase FeCrAl alloy is measured via micromechanical testing in a scanning electronic microscopy at room temperature. Two important factors, the shape and orientation of a pillar, are discussed with respect to the glide resistance and stress-strain ...

Effect of Zr on Initial Oxidation Behavior of FeCrAl Alloys

Oxidation of Metals, 2020
The initial oxidation behavior of Fe–24Cr–10Al (in at%) alloys with and without 0.006Zr or 0.06Zr during heating followed by isothermal oxidation for up to 30 min at 1000 °C was investigated by in situ high-temperature X-ray diffraction using synchrotron radiation and by STEM–EDS analysis.

Performance of an FeCrAl alloy in a high-temperature CO2 environment

Corrosion Science, 2018
Abstract Supercritical CO2 has been suggested as a candidate heat transfer fluid in concentrated solar power plants, but its implementation requires cost-effective materials that can resist corrosion in high-temperature C-rich environments. Alumina-forming alloys are known to resist high-temperature corrosion in oxygen, but little is known about ...

Corrosion of the bonding at FeCrAl/Zr alloy interfaces in steam

Journal of Nuclear Materials, 2018
The interfacial bonding at protective coatings and Zr alloy substrates could have a significant effect on the corrosion behaviors of the coatings. In this work, FeCrAl-Zr couples were fabricated at 900 °C by spark plasma sintering (SPS), and the interfacial bonding of the couples was modified through the addition of Si and/or thermal diffusion at 1100 °

Carbon Erosion of FeCrAl Bulk Alloy by Chlorinated Hydrocarbons

Protection of Metals and Physical Chemistry of Surfaces, 2016
Change in the chemical composition and structure of the FeCrAl alloy surface after various preliminary activations has been studied using scanning electron microscopy. The influence of activation way on alloy reactivity relative to aggressive 1,2-dichloroethane vapors was investigated at 550 and 700°C.

Effect of Ti Addition on Nonmetallic Inclusions in FeCrAl Alloys

steel research international
To investigate the influence mechanisms of Ti addition on inclusions in FeCrAl alloys, a series of experiments and thermodynamic calculations are carried out by controlling Ti additions. In FeCrAl alloys without Ti, inclusions are mainly AlN, and a tiny amount of Al 2 O 3

The spread into terahertz radiation using FeCrAl alloys wires

Materials Letters, 2015
Abstract FeCrAl alloys wires with different Cr contents were investigated as a broadband radiation source for the spectral region from 1100 to 100 cm−1. Due to the change in temperature, the radiation intensity depends on the driven current. Compared with commercial mercury arc lamp and terahertz quantum cascade laser sources, the FeCrAl alloys wires

Characterization of the oxidation-sulfidation of a preoxidized ODS FeCrAl alloy

Proceedings, annual meeting, Electron Microscopy Society of America, 1993
Preoxidation is a common technique used to protect alloys from environmental degradation. A dense, adherent oxide is grown on an alloy before placing it into a more aggressive environment. Thus, under conditions such as the mixed O-S atmosphere found in coal gasification, the rapid formation of sulfide can be avoided.While several studies have looked ...

The Effect of Y on the Strength of FeCrAl Alloy/Sapphire Interfaces

MRS Proceedings, 2002
ABSTRACTThe effect of Y on the interfacial strength of the FeCrAl/sapphire system has been quantitatively measured by the laser-spallation technique in order to understand the ‘reactive element effect’. The presence of Y improved the interfacial strength of the FeCrAl/sapphire interface in the as-deposited state from 330±31 MPa to 686±36 MPa.
