“…Upon the addition of Ti-coated diamond to the Al alloy matrix, the outer α-Ti later enables the wetting of the Al alloy matrix [61]. As a result, the Al 3 Ti phase was formed around the temperature of 590 • C [62,63], as evident from the XRD peaks at 38.46 • and 64.56 • , as shown in Figure 5; similar peaks were observed in other research works [58]. Additionally, an improvement in the peak reflection of the Al 12 Mg 17 can be seen in Figure 5, indicating that either the amount of (Al 12 Mg 17 ) increases or the crystallinity of the (Al 12 Mg 17 ) phase increases with the increase in the Ti-coated diamond content.…”

In this work, porous Al alloy-based composites with varying Ti-coated diamond contents (0, 4, 6, 12 and 15 wt.%) were prepared, employing the powder metallurgy route and using a fixed amount (25 wt.%) of polymethylmethacrylate (PMMA) as a space holder. The effects of the varying wt.% of diamond particles on the microstructure, porosities, densities and compressive behaviors were systematically evaluated. The microstructure study revealed that the porous composites exhibited a well-defined and uniform porous structure with good interfacial bonding between the Al alloy matrix and diamond particles. The porosities ranged from 18% to 35%, with an increase in the diamond content. The maximum value of plateau stress of 31.51 MPa and an energy absorption capacity of 7.46 MJ/m3 were acquired for a composite with 12 wt.% of Ti-coated diamond content; beyond this wt.%, the properties declined. Thus, the presence of diamond particles, especially in the cell walls of porous composites, strengthened their cell walls and improved their compressive properties.

“…However, the poor ductility and high chemical reactivity of Al-Ti alloys are the main factors limiting the industrial-scale production [6][7][8]. Amorphized Al-Ti alloys was found for a wide range of compositions between 25 and 90at% of titanium and MA time between 15 and 200 hours [9,15]. The better properties of these systems can be of great interest to many applications.…”

This paper focuses on the microstructural characterization of Al25Ti75, Al37Ti63, Al50Ti50, Al63Ti37and Al75Ti25powders mixtures prepared by mechanical alloying (MA). The high-energy ball-milling, up to 75 h, of aluminium and titanium powders leads to a nanocrystalline or an amorphous structure. It is showed that a stable amorphous Al–Ti phase with uniform elemental distribution forms after 50 h of milling in Al50Ti50alloy. Heat treatment of the different alloys leads to the crystallization of AlTi3, AlTi, Al2Ti and Al3Ti intermetallic compounds. A comprehensive study by laser granulometry, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and differential scanning calorimetry (DSC) was carried out on the structure, surface morphology and thermal behaviour of the MA Al-Ti mixtures, both of milled and heat treated powders.

“…It has significant advantages such as good wettability and clean interface between the reinforcement and Al matrix [4]. Therefore, in-situ Al 3 Ti/Al alloy has received extensive attentions, and several methods have been developed, such as in-situ casting [5], powder metallurgy [6], friction stir processing [7] and mechanical alloying [8].…”
