“…In the existing production technology, grain refiners (for instance Al-B, Al-Ti-C, Al-Ti-B, together with other intermediate alloys [5]) and Si modifier (such as Na, Sr and RE [6]) are often added to A356 alloy respectively to achieve better granule purification and modification effect [7]. However, it's difficult to control the refining and modification effect, because of the complexity of smelting process [8]. For this reason, many scholars have carried out a lot of research work.…”

“…However, the interaction between Sr and B will inevitably produce SrB 6 compound in the smelt, which enormously reduces the effect of refining and modification of Al-Si alloy [9]. For the sake of making up for the deficiency of the master alloy containing Sr and B elements, Rao et al [11] together with Zhao et al [8] have successively developed the Al-Ti-C-Sr intermediate alloy, and their refining and modification effects have been studied. It is shown that the TiC pellets in the Al-Ti-C-Sr can be used as the heteromorphic nucleus of primary α-Al, and Al 4 Sr can provide the Sr for modification Prime.…”

The physical characters that belong to hypo-eutectic Al-Si alloys are affected by certain important factors including the dimension, distribution together with structure of eutectic Si crystals together with primary α-Al. In this paper, A356-x Al-5Ti-0.62C-1.07La (x=0, 4, 5, 6, 7 wt%) alloys are was prepared by mechanical stirring. The effects of Al-5Ti-0.62C-1.07La intermediate alloy on the microstructures and mechanical properties of A356 alloy are investigated. Results show that the primary α-Al was significantly refined by Al-5Ti-0.62C-1.07La intermediate alloy. The secondary dendrite arm space (SDAS) of unrefined α-Al is approximately 40 μm. When the substance of Al-5Ti-0.62C-1.07La intermediate alloy is 6 wt%, SDAS declines to 10 μm. In addition, the component part of eutectic Si turns from thick acicular/schistose to short rod-like together with a section of pellets. Adding 6 wt% Al-5Ti-0.62C-1.07La intermediate alloy, A356-T6 alloy obtained the best tensile function and hardness. The ultimate tensile strength (UTS), elongation (El) together with Vickers hardness (HV) are 183.5 MPa, 8.2% and 62.3, which is increased by 30.3%, 95.2% and 38.1%, respectively. Furthermore, the variation in mechanical properties change with the development of micro-structure.

A356 alloy was refined with a new master alloy of Al-5Ti-B-10Sr. The microstructure and mechanical properties of the refined A356 alloy with different content of master alloy (0, 0.1, 0.3, 0.5 and 0.7 wt.%) were investigated. The results show that the refining effect becomes stronger as the master alloy content increasing from 0.1 to 0.3 wt.%, and then shows slight decrement until 0.7 wt.%. An optimal combination of the tensile strength (193 MPa) and the elongation (17.8%) of as-cast A356 alloy was achieved with 0.3 wt.% of refining master alloy. Compared to the non-modified A356 alloy, the tensile strength and the elongation were improved by 10% and 242%, respectively.
