Peritectic transformations in crystallization of alloys of the Al-Cr system. I

  • Published:
Soviet Physics Journal Aims and scope

Abstract

Established laws of the nonequilibrium crystallization of aluminum-chromium alloys permit the conclusion that each peritectic horizontal on the diagram of the Al-Cr system (at 725, 930, and 1000°C) corresponds to a region of structural transformation to a liquid extending from aluminum is the vertical of an intermediate compound. Retention of the stability of the high-temperature structural state of the liquid during its cooling predetermines the possibility of a delay in the peritectic transformation, crystallization according to metastable diagrams and, in individual cases, the formation of supersaturated solid solutions based on aluminum.
