Orientation relationship of eutectoid FeAl and FeAl2

Fe-Al alloys in the aluminium range of 55-65 at.% exhibit a lamellar microstructure of B2-ordered FeAl and triclinic FeAl2, which is caused by a eutectoid decomposition of the high-temperature Fe5Al8 phase, the so-called ∊ phase. The orientation relationship of FeAl and FeAl2 has previously been studied by Bastin et al. [J. Cryst. Growth (1978 ▸), 43, 745] and Hirata et al. [Philos. Mag. Lett. ...

The Correlations between the Eutectoid Transformation, Order-Disorder Transformation, and Martensitic Transformation in Cu3Al Binary Alloys

In view of the fact that three kinds of phase transformations, i.e. aneutectoid decomposition β→ α+γ2, an ordering transformation β→ β1, and a martensitic transformation β1→ β' have been observed on isothemlal holding and cooling at different rates from the β region in Cu-Al binary alloys, the author has tried to obtain the T/T/T diagrams in order to show the correlations between these three tr...

Characterization and Morphological Analysis of Pearlite in an Eutectoid Steel

Pearlite is a lamellar product of eutectoid decomposition, which may form in steels and non-ferrous alloys during transformations under isothermal or continuous-cooling (1,2). A pearlite nodule is composed of multiple colonies; each colony has parallel lamellae, which are orientated differently with respect to lamellae in adjacent colonies. This also exhibits a wide range of interlamellar spaci...

Microstructural Evolution of X45CrNiW189 Valve Steel During Hot Deformation

The hot compression tests were carried on X45CrNiW189 valve steel (X45) in the temperature range of 1000– 1200 °C and the strain rate range of 0.004 – 0.5 s-1 in order to study the high temperature softening behavior of this steel. For the exact prediction of flow stress, the effective stress-effective strain curves were obtained from experiments under various conditions. On the basis of experi...

Crucial Mechanism to the Eutectoid Transformation of Wüstite Scale on Low Carbon Steel

It is important to realize the transformation behavior of wüstite because it greatly affects the final structure of the oxide layer and the surface quality of the steel products. In the present study, the transformation behaviors of the wüstite layer are examined under nearly-oxygen-free conditions, to simulate the cooling processes after the hot rolled strip is coiled. As the single phase wüst...
