Development and characterization of an iron aluminide

Oct 31, 2020 Iron aluminides are intermetallic FeAl alloys known for their high temperature corrosion and oxidation resistance, which makes them candidate materials for high temperature applications. In the present work, the formation of an iron aluminide layer on a mild steel substrate by friction stir surfacing of aluminium alloy AA6351 followed by isothermal heat treatment is reported. After Al-alloy ...

Dec 24, 2009 The DSC curve agrees with the TG result. An intense exothermal peak at 605 C is observed. The much higher temperature peak of FeL 4-SBA than that of H 2 L 4-SBA 586 C gives another piece of evidence for the existence of iron complexes in the hybrid materials. TGDSC analysis data of other supported iron complexes are listed in Table 3. It ...

Thermal Analysis of Rubbers and Elastomers

Thermal Analysis of Rubbers and Elastomers

What is Differential Scanning Calorimetry Calorimetry is a technique for determining the quantity of heat that is either absorbed or released by a substance undergoing a physical or chemical change. A DSC measures the difference in Heat Flow Rate between a sample and inert reference as a function of time and temperature.

Most iron ore samples were shown to contain measurable quantities of goethite, with a characteristic dehydration peak in DSC and TG between 200 and 400 C. At higher temperatures, all samples decomposed to produce magnetite with an accompanying mass loss in the TG profile due to the evolution of oxygen. High temperature reaction calorimetry has ...
