Effect of d Metals on the Polymorphous and (Mono) Eutectoid Transformation Temperatures of Binary Titanium, Zirconium, and Hafnium Alloys

Abstract

Phase diagrams of the binary titanium, zirconium, and hafnium alloys with transition metals are analyzed in this work. The stabilizing effect of a d metal on the β phase is shown to depend on the position of the metal in the Periodic Table. The stabilizing effect in titanium alloys increases as the Group number of alloying element increases; the value of the effect is found to vary in accordance with the position of the metal in the Periodic Table. The (mono) eutectoid temperatures of the binary titanium, zirconium, and hafnium alloys are systematized in accordance with the position of alloying metal in the Periodic Table. A significant similarity was found in the regularities of variations of (mono) eutectoid temperatures of the binary titanium, zirconium, and hafnium alloys with different d metals.
