“…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] .…”

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.

“…Compared with Al-Ti-B grain refinemnt, the aggregation tendency of TiC particle is less than that of TiB 2 particle, and also has better grain refinement effect for aluminum alloy with Zr (0.03wt,%), Cr and Mn. Thus, AlTiC is a new generation of grain refinement materials, as a replacement of AlTiB [1][2][3].…”

Abstract. Al-Ti-C alloy is a kind of fine refinement agent. However, the wetting of Al/C interface and TiC synthesis are the key technical problems to be solved in the preparation of Al-Ti-C grain refinement. In this paper, the acoustic cavitation effect was used to improve the wettability of Al-Ti/C interface, and improve the thermodynamic conditions of reaction, and thus the Al-Ti-C grain refinement agent was successfully prepared. The wetting properties of Al-Ti/C interface under different conditions were obtained. The results show that the acoustic cavitation effect significantly influences the wetting process. When the sound intensity is greater than the threshold value, the acoustic cavitation effect produces, and then the complete wetting of Al-Ti/C interface can be realized. At the same time, the high temperature effect of the cavitation also prevents the formation of harmful Al4C3 compound, and changes the way of forming TiC compound which is different from the conventional reaction, and enhances the thermodynamics reactivity of the system to promote the TiC synthesis.

“…Al-Ti-B is most widely used alloy with Ti: B ratios varying from 3:1 to 50:1. Titanium and boron are used to refine primary aluminum grains [14][15][16]. Addition of zirconium as a grain refiner introduces Al 3 Zr trialuminide particles, which are stable, coherent to the aluminium matrix and exhibit a small lattice parameter mismatch with the α-Aland therefore act as efficient heterogeneous nucleants during solidification of aluminium [17][18][19].…”

The effect of Zr addition on the grain refinement of commercial pure aluminium (99.7%) has been investigated in the present study. The results showed that addition of up to 0.3wt. % Zr significantly decreases the average grain size of aluminium from 1100 µm to 162 µm at holding time of 90 seconds. The refining effect of zirconium is attributed to the presence of Al 3 Zr particles in Al-Zr master alloy. These particles are acting as effective heterogeneous nucleating sites for α-Al.
