Abstract

AlCu3 alloy was examined with the triple simple thermal analysis (TETA), the simultaneous thermal analysis (STA), the computer simulation using Thermo-Calc program and with the metallographic analyses. The energy of solidification and melting of the primary and the eutectic phase, and the energy of the Al₂Cu precipitation were determined, and these can be evidently seen from the curves of simultaneous thermal analysis.

Keywords
