Grain refining is considered one of the most important liquid metal processing processes for
aluminum alloys. Three different types of grain morphology are possible: columnar, twin …

The objective of the current work is to establish the conventional mechanisms of grain
refining, and the effect of the refiner-modifier interaction in Al-based alloys on the resultant …

Entrained double oxide films, or bifilms, can seriously alter the structural integrity,
microstructure, and in this way, the mechanical performance of aluminum alloys. Bifilms …

Great attention has been focused on the design of good thermal conductivity and high-
strength Al–Si alloys to ensure the dissipation of heat and load of electronic components. In …

Grain refiner particles, which are intended to induce the formation of fine equiaxed grain
structure during the solidification of aluminum alloys, are prone to settling during the holding …

The melts of the studied alloys were poured into a preheated (450° C) L-shaped rectangular
mold. Samples sectioned from the castings were solution heat-treated at 495° C for 8 h, then …

The present study was carried out on ultra-pure aluminum, 1050, and 356 alloys. The results
revealed that when Al-4% B is added to ultra-pure aluminum, it forms AlB12 and AlB2 which …

Aiming at the problem of unclear grain refinement mechanism in aluminium alloys, Al n B n
(n= 2–12) clusters and Al–3B alloy were studied by density functional theory methods. The …

Thermodynamic theory was used to calculate the formation temperature and site fraction of
MC carbides in Fe–C–Ni–V–Ti system. The calculation results showed the theoretical …

Since the industries are called to produce environmentally friendly products, the research is
moving toward new improved materials. In this panorama, aluminium alloys find applications …
