Alloys can have a microstructure consisting of solid solutions, where secondary atoms are introduced as substitutionals or interstitials in a crystal lattice. Important for the uniqueness of steel is the allotropy of ironthat is, its existence in two crystalline forms. Stainless steels, also known as inox steels or inox from French inoxydable (inoxidizable), are steel alloys, which are very well known for their corrosion resistance, which increases with increasing chromium content. The secret to steel is getting a precise and even carbon concentration, forming the right phase at the correct heat, quenching at the correct speed without introducing impurities, and then tempering to adjust the hardness / brittleness ratio.

To simulate the 9 at% FeCr alloy, two of the Cr atoms are placed in the two bottommost atomic layers (maximally far from each other). On both ends were connections to a power source, and the ring was heavy enough to pull the steel wire down in the center, with the slack. C atoms are small, but the diameter of C atoms is estimated to be 56 % of the diameter of Fe atoms in austenite. Figure 6.7B.1: Different atomic mechanisms of alloy formation, showing pure metal, substitutional, and interstitial structures. Steel is an alloy consisting of Fe with a small amount of C. Elemental Cr can be added to steel to make the steel less likely to rust; Cr atoms react with oxygen in the air to form a nonreactive layer of chromium oxide on the surface of the steel, preventing the oxidation of underlying Fe atoms. In metabolism, the carbon atoms in the fatty acids are oxidised, producing acetyl-CoA molecules. Well, if the metal is heated to >750C and then cooled to room temperature slowly, the molecules would rearrange to alpha ferrite steel and it would be brittle.
