“…The reaction between water vapor and aluminum also generates hydrogen (Salazar et al 2016 , 2005 ). Others authors have proposed hydrogen production using iron aluminides (López-Miranda and Rosas 2019 ; Romero-Romero et al 2014 ; García de León et al 2013 ). This suggests that this method could be used to produce hydrogen; however, it requires more studies.…”

Graphic abstract Today, Fe–Al intermetallic compounds are receiving a great interest from the mechanical, aerospace, and biomedical industries. A novel production process for Fe–Al intermetallic powders based on the generation of metallic tapes by rapid solidification and disintegration by water vapor was proposed. In this research work, a comparison is made between the energy required to manufacture of Fe–Al powder using the aforementioned process and one of the most commonly used manufacturing processes within the industry such as mechanical alloying. In addition, some other benefits of the proposed manufacturing process are analyzed. To carry out this comparison, the theoretical equations that take into account the most important variables involved during the process such as the type of material and hardness, the initial and final particle size, the grinding stages and the heating of the treatment powder were considered. In the case of calculating the energy required for the new proposed process, the two main stages were considered such as (1) the production of FeAl metal tape and (2) the subsequent transformation of the tape into powder by means of injection water vapor. For the first stage, the CASTRIP process is considered, and for the second stage, the energy required for the generation steam. Although the calculations may have certain limitations, it is obvious that the energy required to Fe–Al powder production using the new process is much lower than that required by mechanical alloying, resulting in at least three orders of magnitude lower (2.75 × 10 6 versus 2.206 × 10 9 kJ/ton). This lower energy implies considerable economic savings in the production process. On the other hand, when using water as a grinding medium during the process, it results in less environmental and acoustic pollution, less manipulation risks for humans and finally, no harmful agents or additives are used, making the proposed process sustainable.

“…However, while some studies report the formation of a mixed crystalline and amorphous structure as observed at the end of the 2 θ positions, others claim that the weld zone and HAZ produced are fully crystalline [16]. Apart from Aluminium matrix, the peaks also correspond to the peaks of Al 4 Cu 9 [17], Al 4 Li 9 [18], Al 2 CuMg [19], FeAl 2 [20], Al 2 Cu [21], Al 8.9 Li 1.1 [22], AlLi [23] and Mg 2 Si [24,25], suggesting their possible presence in the weldment. This confirms that the formation of multiple phases does not affect the weld zone strength.…”

In this study, two grades of Aluminium–Lithium alloys: AA8090 and AA2050 have been selected. Butt joints were produced using the Rotating arc welding process (SpinArc™) with ER4043 filler. Two different groove joints, Square Butt and V-Groove, were used during the process. The joints were subjected to analysis of microstructure, mechanical properties and electronic work function. A correlation was brought out between all these tests. The microstructure analysis showed the formation of Mg2Si and Al2Cu eutectics. It was also found that the joint made using the Square Butt joint exhibited greater weld strength and enhanced work function. Electron microscopy and XRD analysis revealed the presence of different strengthening precipitates at various zones.

Intermetallic Fe-Al compounds have become very interesting materials due to their properties, such as good corrosion resistance, high-temperature resistance, high resistance/weight ratios, creep resistance, good wear resistance, and low cost, including some applications where they could replace stainless steels. However, their low ductility at room temperature has limited their use. One of the solutions is to generate powders of these intermetallics and press them in the wished form. Current production methods of this type of powders are very high energy-consuming, polluting, and harmful for handling for human beings. Because of the environmental situation in our planet, it is necessary to develop more environmentally friendly processes, which have lower energy requirements. Therefore, a comparison of a novel water vapor-based FeAl powder manufacture process with Mechanical Alloying (MA), one of the most commonly used processes to produce this type of powder is made in this work. This comparison aims to focus on the advantages of the novel process concerning MA, the last one, considering environmental as well as energy criteria.
