Relationship between the types of binary alloy phase diagrams of VIII and IB group elements and the Mendeleev numbers

摘要

The relationship between the types of binary alloy phase diagrams of VIII and Ib group elements and the Men- deleev numbers was discussed for the first time using the VIII and IB group elements as solvent metals (A) and the other elements as solute metals (B), basesd on their alloy phase diagram types. The Mendeleev numbers of the solvent metals and the solute metals were expressed as M_A and M_B, respectively. A two-dimension map of M_A/M_B was drawn. It is indi- cated that there is an oblique line in the map, which divides the binary alloy phase diagram types of solvent metals into two symmetry parts, the phase diagram types of the other elements with solvent metals located at the above or down of the line respectively, while on the line, △M = 0.
