Request PDF | High-Temperature Oxidation Behavior of Iron–Chromium–Aluminum Alloys | The detailed oxidation behavior of Fe–10Cr alloys, containing aluminumin the range of 2–8% by weight.
The detailed oxidation behavior of Fe–10Cr alloys, containing aluminumin the range of 2–8% by weight, was studied in pure oxygen at 1 atmpressure. The investigations were performed over the temperature range950–1050°C under cyclic conditions (3-hr cycles) in each case. Thecyclic-oxidation resistance, as measured by the specific weight-gain values,was observed to.
2 天前 · Iron Chrome Aluminum alloys form a light grey Aluminum Oxide (Al2O3) at temperatures above 1,000°C (1,832°F) which increases corrosion resistance as well as acts as an electrical insulator. The oxide formation is considered self-insulating and protects against short circuiting in the event of metal to metal contact.
A family of iron-chromium-aluminium (FeCrAl) alloys consist mainly of iron, chromium (12-27%) and aluminium (3,5 – 5,5%) and are used in a wide range of resistance and high-temperature applications. These alloys are known for their ability to withstand high temperatures (up to 1425°C (2600°F)) and having intermediate electric resistance (1.
The constitution of iron-chromium -aluminum alloys was investigated employing high-purity materials. Ternary sections illustrating the results are presented. The limits of the alpha-plus-sigma region are found to extend from 33 to 63 wt.% chromium at 600 C. At 750 C these limits decreasc to 38 and 57 wt.% chromium.
