Unary (pure substance) and binary phase diagrams are easy to appreciate on two-dimensional graphics. Not so for ternary diagrams. Or more realistically, for materials containing very many elements. See here what is possible.

$Atomic mechanism of acicular ferrite transformation in steels Non-metallic inclusions are anathema when it comes to the design of strong steels because they become the initiation sites for fracture. Huge efforts have been made devoted to making clean steels - the oxygen concentration of a hard bearing steel is routinely less than 10 ppm. However, there are other structural steels that have to be welded where the localised heat input generates microstructures in the heat-affected zone that are undesirable. The alloys that are used to deposit the weld must have good properties in the as-cast state. In both of these circumstances, specific non-metallic inclusions are a positive boon in that they provide substrates for the intragranular nucleation of bainite. As a consequence, highly organised sheaves of bainite are altered into a more chaotic arrangement that frequently deflects propagating cracks and hence enhances the toughness. This is the so-called acicular ferrite that is the subject of this lecture.$

$Chemical potential - a simple explanation The meaning of chemical potential is explained in the context of the thermodynamics of solutions. For more details see: https://www.phase-trans.msm.cam.ac.uk/teaching.html The partial differential with respect to mole fraction of A while keeping that of B constant should really be in terms of the number of moles of A while keeping those of B constant.$
