“…Table 3 demonstrates the experimental design and predicted model UTS strength, RSM findings of tensile strength responses were generated after multiple number of experiments which investigated the parameters of preheating temperature, ZrO 2 and B 4 C volume fraction proportions. The presented pareto chart determines the factors magnitude which are crossing the line reference where, the reference lines confirm that the investigated parameters are significant absolute values cause interactions between parameter towards to the UTS materials strength [ 2 , 49 , 50 ].…”

“…There are several techniques that are associated with SPD, including equal channel angular pressing (ECAP) hot extrusion, multiaxial deformation, conformation, twist extrusion, friction extrusion, high-pressure torsion, forging, accumulative roll bonding, rolling, and other methods. A common SPD technique is the equal channel angular pressing (ECAP), which uses the ECAP die at different angles [50]. The ECAP is flexible and it has been deployed in combination with hot extrusion, which led to the choice of ECAP in combination with hot extrusion.…”

Solid-state recycling is a direct conversion method for producing metal chips, whereas the materials are plastically deformed into the final product without melting, offering lower energy consumption and metal waste. This technique was reported for fabricating aluminium-zirconium oxide (Al-ZrO2) composite and it was widely used to avoid metal chips bounding at high temperatures during the extrusion process. Aluminium alloy (AA7075) is known for its high yield strength of more than 500 MPa under optimum ageing conditions. However, AA7075 can be further reinforced by zirconium oxide nanoparticles when needed for high-performance applications. Hot extrusion is used to obtain better mechanical properties of composite materials. The equal channel angular pressing (ECAP), a severe plastic deformation technique, was recently used to produce bulk and light recycled metal chips, such as porosity-free and ultra-fine-grained aluminium nanocomposites (ANCs). Heat treatments (HT) and ECAP post hot extrusion are mostly incorporated to improve tribological and mechanical properties and aluminium nanocomposite bonding efficiency. In this review, ANCs’ fabrication by the hot extrusion technique and the effects of ZrO2 nanoparticle are duly summarised and discussed. Furthermore, this review emphasises the importance of using HT and ECAP techniques to acquire better metal alloy incorporation, such as AA7075-ZrO2. Interestingly, owing to the lightweight properties and superior performance of AA7075-ZrO2, it was reported to be suitable for fabricating many drones’ parts, military equipment, and some other promising applications.

“…This corresponds to a study on the effects of samarium addition to the AZ61 (Mg-Al-Zn) magnesium alloy, resulting not only in a refined microstructure but also in improved ultimate tensile strength and elongation. However, excessive Sm addition could cause the coarsening of grain, leading to the decline of strength and plasticity (Rady et al, 2019;Al-Alimi, Lajis, and Shamsudin, 2017). Samarium also has unique properties that make it useful for various applications other than as an alloying element in metals.…”

The influences of rare earth (RE) samarium (Sm) added contents to ZRE1 (Mg-Zn-Zr) magnesium (Mg) cast alloy over strength properties to be investigated. Sm at 0.5, 1.0, 1.5, and 2.0 wt.% were added separately as an alloying element to ZRE1 alloy. Optical Microscope (OM), X-ray powder diffraction (XRD), and scanning electron microscope Energy-dispersive X-ray (SEM/EDS) were used to investigate the microstructure of alloy, while mechanical properties investigated include Ultimate Tensile Strength (UTS)and Micro-Hardness (MH) tests. The result revealed that as the Sm level reached 1.5 wt.%, the grain size decreased by 20.9 %. Additionally, UTS and Yield Strength (YS) showed improvements of 8.5 % and 7.9 %, respectively, with the addition of 1.5 wt.% of Sm. In addition, elongation and hardness have been improved by 32.3 % and 10.9 % respectively at 1.5 wt.% Sm addition. Mg-Zn-Ce-Sm was formed as a new phase upon the addition of Sm and was detected via XRD analysis. The addition of Sm to the ZRE1 alloy had significant effects on the refinement of the material's microstructure, leading to an increase in its mechanical and physical properties. Therefore, the new ZRE1-RE magnesium alloy was developed.
