Kurzfassung:
Experiments are performed to investigate the effect of thermal exposure on the phase evolution of Al–12Si–3.8Cu–2Ni–1Mg aluminum alloy. The phase formation during solidification is carried out by means of thermodynamic simulations based on JMatPro software. The results show that as‐cast alloy consists of α‐Al, Si, δ‐Al 3 CuNi, Q‐Al 5 Cu 2 Mg 8 Si 6 , AlSiFeNiCu, and Ti 2 Al 20 Ce phases. The microstructure observations show that the block‐shape Ti 2 Al 20 Ce phase is stable at 425 °C. Combined with DSC analysis, parts of AlSiFeNiCu phase have dissolved after thermal exposure at 425 °C for 200 h. Besides phase transition, solubility of alloy elements plays an important role in Vicker's hardness during thermal exposure process as well.
