Metals weaker than iron

Web13 mrt. 2024 · Iron is fairly reactive; in moist air. it oxidizes to form rust, a mixture of iron oxides. Oxidizing acids like nitric acid react with iron to form a passivating layer on the surface of the iron; this passivating layer protects the iron underneath from further attack by the acid, although the brittle oxides of the layer can flake off and leave the interior metal … WebQuenching is an ancient method of rearranging the atomic structure of a material. Quenching is the process of rapidly cooling a material (usually a metal) in order to obtain desirable mechanical properties like increased strength and hardness. Most people think quenching is just dunking red-hot steel into a bucket of water, but materials ...
