“…When the Zn content increased from 4.4% (mass fraction) to 7.2% (mass fraction), the ultimate tensile strength (UTS) of the Al-xZn-2.3Mg-1.7Cu alloy increased from 212.15 MPa to 248.05 MPa, which is an increase of 16.92%; the elongation (elongation, EL) increased first and then decreased with the increase in Zn content. And the maximum elongation was 8.78% when x = 5.8 [11]. The increase in the number of MgZn 2 strengthened phases, and the changes in the shape, number and size of the intercrystalline eutectic phases improved the tensile strength.…”

An Al–Zn–Mg–Cu alloy has high specific strength, good corrosion resistance, fracture toughness and fatigue resistance. It is one of the most important structural materials in the fields of aviation, aerospace, weapons and transportation; in particular, it plays a huge role in the field of aerospace. In order to optimize the strength, toughness and corrosion properties of an Al–Zn–Mg–Cu alloy, the focus of research on this alloy has always been on the alloying process. The effects of the main alloying elements, trace alloying elements and rare earth elements on the microstructure and properties of Al–Zn–Mg–Cu alloys are briefly introduced in this paper, and future research directions are proposed.

“…Theoretically, the strength of these alloys can be augmented by approaching theoretical limits of Zn content and maintaining an appropriate Cu to Mg ratio; however, practical constraints arising from alloy solubility limit this pursuit. Specifically, the development of coarse reticular second phases, leading to diminished mechanical performance, is often culminated by Zn content exceeding 8 wt.% in conventional cast alloys [125,126]. Contrastingly, the solubility of alloying elements is enhanced by the spray-forming process, thereby facilitating the precipitation of strengthening η ′ phases during subsequent heat treatment and aging processes, ultimately elevating the mechanical properties [127,128].…”

Spray forming is a manufacturing process that enables the production of high-performance metallic materials with exceptional properties. Due to its rapid solidification nature, spray forming can produce materials that exhibit fine, uniform, and equiaxed microstructures, with low micro-segregation, high solubility, and excellent workability. Al-Zn-Mg-Cu alloys have been widely used in the aerospace field due to their excellent properties, i.e., high strength, low density, and outstanding machinability. The alloy manufactured by spray forming has a combination of better impact properties and higher specific strength, due to its higher cooling rate, higher solute concentration, and lower segregation. In this manuscript, the recent development of spray-formed Al-Zn-Mg-Cu alloys is briefly reviewed. The influence of hot working, i.e., hot extrusion, hot forging, and hot rolling, as well as different heat treatments on the property and microstructure of spray-formed Al-Zn-Mg-Cu alloys is introduced. The second phases and their influence on the microstructure and mechanical properties are summarized. Finally, the potential in high-temperature applications and future prospects of spray-formed aluminum alloys are discussed.

reported the comparison results in the range of 0-10 based on the equations. The ideal case demonstrates the highest possible level of efficiency, and lifespan, specific power and energy, energy and power density, technical maturity, and the lowest possible power and energy capital cost, self-discharge rate, and environmental impact. [13] Figure 1c represents the PCMs' characteristics.In a previous review, Sadeghi (2022), discussed the thermal energy management of batteries and high-heat-flux electronic devices, and the capability of the TES systems. [2] Costa and Kenisarin (2022) produced a database of metallic PCM's thermophysical features and potential impact in diverse fields, for instance, bioengineering, electronics, solar energy storage, cooling and heating, and beyond. [8] Chavan (2022) covered the recent progress in TES and its usages such as waste heat recovery, solar-based TES, building applications, thermal comfort, heavy electronic equipment cooling, vapor absorption refrigeration (VAR), and Heating, ventilating, and air-conditioning (HVAC) applications. [14] An increasing number of recent research addresses the use of PMCs in human body, detection or sensing, biological, barcoding, drug delivery, and medical applications. However, there is no review comprehensively discussing the life science applications of TES and PMCs materials. Based on our literature survey we concluded that a review of the life science applications of PCMs is a required reference. Besides, the evaluation and safety aspects of TES will be explored in this review. Furthermore, the challenges and recommendations of PCM applications will be addressed in order to assist energy technologists and streamline future research.
