Enhanced Fluidity of ZL205A Alloy with the Combined Addition of Al–Ti–C and La

Abstract: The effects of Al–Ti–C and La on the fluidity of a ZL205A alloy after separate and combined addition were studied by conducting a fluidity test. The fluidity of the ZL205A alloy first increased and then decreased with the increasing addition of Al–Ti–C and La; it peaked at 0.3% and 0.1% for Al–Ti–C and La, respectively. The combined addition of Al–Ti–C and La led to better fluidity, which increased by 74% compared with the base alloy. The affecting mechanism was clarified through microstructure characterizatio… Show more

“…Thus it is necessary to control the solidification structure of the large-sized 6061 alloy billets. Currently, the grain refiner, such as Al-Ti-B [6][7][8], Al-Ti-C and Al-Ti-Re [7,[9][10][11] master alloy is added into the melt before solidification, as heterogeneous nucleation sites to refine the solidification structure of the large-sized DC-casting billets. But it is well known that most of the heterogeneous nucleation sites become inclusions [12].…”

“…It has been shown that the addition of Al–Ti–C and La can improve the fluidity of ZL205A alloy [ 21 ] and refine the grains of pure aluminum [ 22 ]. However, can the composite addition of Al–Ti–C master alloy and the rare-earth element La improve the high-temperature performance of ZL205A?…”
