“…Finally, MELD is instrumental in material independence and scalability in numerous sectors, such as aerospace, defense, and turbomachinery engineering. MELD-produced AMCs have a uniform distribution of reinforcement particulates, which prevent local stress concentration, interfacial delamination, corrosion, and fracture initiation, thereby improving the composite materials' mechanical properties and performance [152].…”

Shape Memory Alloys (SMAs) are metallic materials with unique thermomechanical characteristics that can regain their original shape after deformation. SMAs can be used in various industries such as consumer electronics, automobile parts, aircraft components, and biomedical devices. In this paper, we review the current state of the art of SMA fabrication and their application in the aerospace, healthcare, and aerospace industries. Specifically, we focus on the influence of manganese (Mn) addition on Cu-Al-Ni shape memory alloys' structure, mechanical characteristics, and corrosion behavior, focusing on the incorporation of small and medium-sized enterprises (SMEs) in the analysis of cu-aluminum alloys. This study explores the integration of SME and superelasticity, critical phenomena in SMA behavior, and can be utilized to develop and evaluate SMA-based devices and structures, as well as to understand the mechanism behind SMA actuation and develop improved materials. FEM simulations are crucial for optimizing designs and enhancing performance in sectors like aerospace and healthcare. FEM simulations can also be used to predict the stress and strain of SMA-based devices and structures. This can help to reduce cost, improve efficiency, and reduce the risk of failure. Additionally, FEM simulations can help to identify potential weaknesses in SMA-based designs and suggest modifications or improvements.

“…Solid-state additive manufacturing offers several advantages over other additive manufacturing (AM) technologies [1][2][3][4][5][6]. Of particular note are the following: Other increasingly important benefits in terms of environmental objectives include the direct recycling of material normally considered waste, such as machine chips [3], and the possibility of high-quality part repair [5,7]. The main disadvantages of friction-based solid-state additive processes are the comparatively high process forces stemming from their solely mechanical working principles [8].…”

Additive friction extrusion deposition (AFED) is a recently developed additive manufacturing technique that promises high deposition rates at low forces. Due to the novelty of the process, the underlying phenomena and their interactions are not fully understood, and in particular, the processing strategy and tool design are still in their infancy. This work contributes to the state-of-the-art of AFED through a comprehensive analysis of its working principles and an experimental program, including a representative sample component. The working principle and process mechanics of AFED are broken down into their individual components. The forces and their origins and effects on the process are described, and measures of process efficiency and theoretical minimum energy consumption are derived. Three geometrical features of the extrusion die were identified as most relevant to the active material flow, process forces, and deposition quality: the topography of the inner and outer circular surfaces and the geometry of its extrusion channels. Based on this, the experimental program investigated seven different tool designs in terms of efficiency, force reduction, and throughput. The experiments using AA 6061-T6 as feedstock show that AFED is capable of both high material throughput (close to 550 mm3/s) and reduced substrate forces, for example, the forces for a run at 100 mm3/s remained continuously below 500 N and for a run at 400 mm3/s below 3500 N. The material flow and microstructure of AFED were assessed from macro-sections. Significant differences were found between the advancing and retracting sides for both process effects and material flow. Banded structures in the microstructure show strong similarities to other solid-state processes. The manufacturing of the sample components demonstrates that AFED is already capable of producing industrial-grade components. In mechanical tests, interlayer bonding defects resulted in more brittle failure behavior in the build direction of the structure, whereas in the horizontal direction, mechanical properties corresponding to a T4 temper were achieved.
