“…In addition to Al 3 Ti and TiC secondary phases (the same as those of Al-Ti-C refiners), Al-TiO 2 -C refiners contain Al 2 O 3 particles that can impede grain growth. This improves the grain refinement effect of these refiners [11].…”

A series of new Al-TiO2-C-Y2O3 aluminum alloy grain refiners with different Y2O3 content was prepared by exothermic dispersion method using Al, TiO2, C, and Y2O3 powders as raw materials. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDS) were used to investigate the effect of Y2O3 content on the structure of the Al-TiO2-C refining agent as well as the effect of the Al-TiO2-C-Y2O3 refining agent on the grain size and mechanical properties of an Al-5Cu alloy. The results showed that the Al-TiO2-C-Y2O3 refiner was composed of Al2O3, TiC, Al3Ti, Al5Y3O12, and Al20Ti2Y phases. The refiner with 4% Y2O3 content exhibited the best Al-5Cu alloy refining effect, achieving a grain size of about 210.5 µm. This was about 42% of the grain size of the original Al-5Cu alloy. Moreover, this refined Al-5Cu alloy exhibited the best mechanical properties, with a tensile strength and elongation of 173.13 MPa and 9.19% respectively. This was a 20.9% and 83.8% improvement compared with the original Al-5Cu alloy. However, with a further increase in Y2O3 content, an Al5Y3O12 phase was preferentially formed. This led to a decline in Al20Ti2Y phase content and a correspondingly weaker refinement effect.

“…The transition phase of rare-earth ErC 2 is not stable at high temperature; it will form TiC and rare-earth [Er] with free [Ti]. [10] [Er] has high activity and will quickly form a stable rare-earth phase Al 20 Ti 2 Er with Al 3 Ti produced by reaction (2), as shown in reaction (6).…”

“…In recent years, in addition to the conventional Al–Ti–C/B refiner, various new refiners have also been studied, such as Al–Nb system, Al–TiO 2 –C system, etc. [ 6 ] . Among them, the Al–TiO 2 –C refiner not only contains Al 3 Ti, TiC, and other nucleation phases, but also generates Al 2 O 3 that inhibits the growth of aluminum grains, so it is expected to further improve the refining performance.…”

A new type of Al–TiO2–C–XEr2O3 aluminum alloy refiner is prepared by exothermic dispersion method, and the effect of different Er2O3 content on the structure and refinement effect of Al–TiO2–C refiner is studied by scanning electron microscope (SEM), X‐ray diffraction (XRD), and other methods. The results show that the refiners are composed of Al3Ti, TiC, Al2O3, Al20Ti2Er, and Al5O12Er3 phases. As the content of Er2O3 increases, the Al3Ti phase changes from flaky to massive. The amount of Al2O3 decreases, and the content of Al5Er3O12 increases and is dispersed in the matrix. When the content of Er2O3 in the refiner is 6%, the Al–5Cu alloy has the best refining effect. The grain size of the Al–5Cu alloy is refined from 500 to 180 μm, and the grain size can be reduced by 64%. At the same time, the tensile strength of Al–5Cu alloy is tested, and the results show that when the content of Er2O3 in the refiner is 6%, the tensile strength is the highest, which is 189.7 MPa. This is consistent with the theoretical results.

In order to develop novel high damping materials with excellent compressive mechanical properties and energy absorption capacity to meet the needs of buffering and vibration reduction in various fields, epoxy resin (EP) filled foam Zn-22Al (ZA22) composites were fabricated for the first time. EP can significantly improve the damping and compressive mechanical properties of the ZA22 foam due to the superposition of multiple damping sources and the support of EP to pores, respectively. However, the filling of EP will lead to brittleness in the compression process of the composites. It is found that the addition of multi walled carbon nanotubes (MWCNTs) or multilayer graphene (MLG) to EP can efficiently improve the toughness of the composites because of the increased energy consumption in the fracture process of EP, and the damping can also be further improved due to the increased interface density and the amount of polymer chains involved in friction.
