Abstract:

Magnesioferrite-periclase microstructures can be correlated to their thermal history. Grain boundary precipitation occurs at higher temperatures, whereas a Widmanstatten precipitation is favored at lower temperatures. Magnesiowustite which is cooled slowly through the solubility limit will first produce magnesioferrite at the grain boundary, followed by a Widmanstatten precipitate of magnesioferrite within the grains. Prolonged heat treatments at any temperature favor the spheroidization of the magnesioferrite within the periclase matrix. Author
