context: Single-phase alloys are so-called solid solutions or solid solutions. There are two types of solid solutions: intermediate and replacement solutions. In an intermediate type alloy, the alloy atoms are located in the metal lattice between the metal atoms. A prerequisite for such a mixture is that the spacer atoms are small enough. Suitable atoms include, for example, carbon, oxygen and nitrogen.
