Micrograph of eutectoid steel with a carbon content of 0.8 % (C80)

Phase transformations of steels in solidified state (metastable system)

Depending on the carbon content, further phase transformations take place in the steel in the solidified state. The cooled microstructure consists of pearlite and ferrite. https://youtu.be/b581J_SmCM4 Introduction As explained in the article Microstructure formation...

Microstructure formation of steels during solidification

Steels solidify as solid solutions. The face-centered cubic lattice structure with the embedded carbon atom is called austenite. https://youtu.be/b581J_SmCM4 Introduction In principle, steels are binary systems consisting of the host element iron and the...

Comparison of phase transformations in steels

Phase transformations in steels can be compared to those of solid solutions (completely soluble) and crystal mixtures (completely insoluble). https://youtu.be/b581J_SmCM4 The figure below shows steel part of the iron-carbon phase diagram of the...
