摘要: Abstract The stress development in the iron oxide scale formed on pure Fe during isothermal oxidation at 700 °C followed by transformation 500 or 380 °C was measured situ high-temperature X-ray diffraction with sin2ψ method. eutectoid resulted compressive generation Fe3O4 and structure. This relaxed heat treatment after reaction. ascribed primarily to volume changes associated and/or reduction of interfaces, precipitation,
