“…The grain refinement efficiency has been shown in late 1940s to increase markedly when B is also added to molten aluminium, allowing the same level of refinement at much lower Ti additions [6]. Al-Ti-B master alloys have thus been the standard grain refiners for aluminium alloys eversince [7][8][9][10][11]. These grain refiners offer a remarkable performance in the continuous and semi-continuous casting of wrought alloys, yet fail to meet the expectations in the case of aluminium foundry alloys [12,13].…”

“…The TiAl 3 and TiB 2 particles can agglomerate into larger particles during the standing process, and the effect of grain refinement can be invalid six hours after adding them into the liquid metal. In order to avoid the agglomeration of TiB 2 during the standing process, Al-Ti-C, Al-Ti-C-B, Al-Ti-C-RE and Al-Ti-B-RE master alloys were developed [46][47][48]. Doheim et al [49] evaluated the Al-Ti-C master alloys as grain refiner for aluminium alloys.…”

Aluminum has been the secondly main metallic material in the world, whose mechanical properties are very important for industrial applications. The sizes and shapes of grains are important in determining the performance in structural applications. How to control the microstructure during solidification process has been a research focus. This paper gives an overview on the recent progress in microstructure control for aluminium alloys solidification process, and introduces the different methods to control the microstructure in detail. The mechanisms of microstructure control for different methods are also discussed. Finally, a brief prospect on future work is presented.

“…In the past two decades, aluminum grain refinement is mainly accomplished by a Al-Ti-B grain refiner [3][4][5] . However, there are many problems in the application of Zr/Cr alloys and boride agglomeration [6][7][8] . As a result, some alternative choices were studied, such as Al-Ti-C and Al-Ti-C-B grain refiners [8][9][10][11] .…”

However, due to the poor wettability between liquid aluminum and graphite, Al-Ti-C grain refiner production is still a key problem in the aluminum industry 12,13 .…”

It is well known that the mechanical properties of commercial pure Al are influenced by size of α-Al dendrites. In the present work, Al-5Ti-0.62C-0.2Nd grain refiner was prepared by a pure molten aluminum thermal explosion reaction, and its effect on grain refinement and mechanical properties of commercial pure Al was investigated. Microstructure and phase composition show that Al-5Ti-0.62C-0.2Nd grain refiner consists of α-Al, granular TiC, lump-like TiAl 3 , and block-like Ti 2 Al 20 Nd. Grain-refining tests on commercial pure Al show that an Al-5Ti-0.62C-0.2Nd grain refiner has better refining performance compared with Al-5Ti-0.62C grain refiner. With addition of 0.2-wt.%-Al-5Ti-0.62C-0.2Nd grain refiner, the average grain size of commercial pure Al can be refined from roughly 2800 to 155±5 µm effectively, and it has higher resistance to grain-refinement fading. On account of the grain refinement, the tensile strength and elongation are increased by approximately 18.3% and 83.5%, respectively.
