About Alloying of Aluminum Alloys with Transition Metals

An attempt is made to advance Elagin's principles of alloying of aluminum alloys with transition metals (TM) such as Mn, Cr, Zr, Ti, V with allowance for the ternary equilibrium and metastable Al - TM - TM phase diagrams. The key moments in the analysis of the phase diagrams are the curves (surfaces) of joint solubility of TM in aluminum, which bound the range of the aluminum solid solution. It is recommended to use combinations of such TM (two and more), the introduction of which into aluminum alloys widens the phase range of the aluminum solid solution.
