“…The phase enriched in Fe is observed near the Fe-based alloy cores. Previously, the separation of the reaction products into layers was observed by Yu et al [33,34]. The formation of layers with compositions close to NbAl3 and NiAl3 was observed when an Al-30 wt.% amorphous Ni60Nb40 alloy composite was annealed at 640 ºC.…”

In the area of metal matrix composites, novel reinforcing options are currently being evaluated. Particles of amorphous alloys present an interesting possibility to reinforce soft metals. In the present work, the interaction between Fe66Cr10Nb5B19 metallic glass and aluminum during Spark Plasma Sintering (SPS) was studied for the first time. In order to trace the phase and microstructural changes upon sintering, mixtures containing 20 vol.% and 50 vol.% of metallic glass were subjected to SPS at 500-570 ºC. After SPS at 500 ºC, no reaction layer between the metallic glass particles and aluminum was observed. After SPS at 570 ºC, a reaction layer containing Fe2Al5 and FeAl3 formed around the Fe-based cores. The Vickers hardness of composites obtained from mixtures containing 20 vol. % Fe66Cr10Nb5B19 at 540 ºC was 75 HV and increased to 280 HV after sintering at 570 ºC due to the formation of thicker reaction layers at the interface.The hardness of the composite sintered from the mixture containing 20 vol. % Fe66Cr10Nb5B19 at 570 ºC was between the values predicted by Reuss and Voigt models.Comparison of results of SPS of the powder mixtures with those of SPS of a precompacted pellet and electric current-free annealing suggests that local heating at the interface caused by interfacial resistance may be an important factor influencing the reaction advancement at the interface and the formation of Al-containing intermetallics.

Metallic-glass-reinforced metal matrix composites are a novel class of composite materials, in which particles of alloys with an amorphous structure play the role of reinforcement. During the fabrication of these composites, a crystalline metal is in contact with a multicomponent alloy of an amorphous structure. In the present work, the morphological features of the reaction products formed upon the interaction of Fe66Cr10Nb5B19 metallic glass particles with aluminum were studied. The composites were processed via spark plasma sintering (SPS), hot pressing or a combination of SPS and furnace annealing. The reaction products in composites with different concentrations of the metallic glass and different transformation degrees were examined. The products of the interaction of the Fe66Cr10Nb5B19 metallic glass with Al were observed as dense layers covering the residual alloy cores, needles of FeAl3 protruding from the dense shells as well as needles and platelets of FeAl3 distributed in the residual Al matrix. The possible role of the liquid phase in the structure formation of the reaction products is discussed. The formation of needle- and platelet-shaped particles presumably occurred via crystallization from the Al-Fe-based melt, which formed locally due to the occurrence of the exothermic reactions between aluminum and iron. At the same time, aluminum atoms diffused into the solid Fe-based alloy particles, forming an intermetallic layer, which could grow until the alloy was fully transformed. When aluminum melted throughout the volume of the composite during heating of the sample above 660 °C, a similar microstructure developed. In both Al–Fe66Cr10Nb5B19 and Al–Fe systems, upon the reactive transformation, pores persistently formed in locations occupied by aluminum owing to the occurrence of the Kirkendall effect.

“…6 Accordingly, liquid state processing of AAMCs comprised melt infiltration, 7–9 and solid state processing included friction stir processing, 10 equal channel angular pressing (ECAP), 11 and powder metallurgy (PM), which in some cases was followed by post processing (hot pressing or extrusion). 12–23 In Table 1, considering the literature survey on AAMCs manufacturing (the survey does not contain the amorphous-nanostructure reinforcing AMC), most of prior studies are focused on solid state processing, particularly PM methods with various sintering conditions and fewer on liquid state processing due to the limited thermal stability of glassy reinforcement. As is well known, PM technology is a complex and high cost process, and unsuitable for fabricating large-sized parts with complex geometry.…”

In the present study, the semisolid forming has been proved to be effective in fabricating amorphous reinforced aluminum matrix composite of high quality with appreciable mechanical properties. In other words, the Ni60Nb40 glassy reinforcement in 520.0 aluminum matrix composite was successfully fabricated via powder thixoforging without altering the glassy nature. Most prior studies are focused on solid state (powder metallurgy). Subsequently, the use of glassy particles with high crystallization temperatures provides processing the composite at higher temperatures. Considering the powder thixoforming benefits, we open a door to another way of manufacturing high-efficient amorphous reinforced metal matrix composite with brilliant mechanical properties. In monolithic matrix, the alloy produced via powder thixoforging hardness and compression yield strength reached 223(HV) and 747 MPa compared to as cast condition increase of 116% and 228%, respectively. Additionally, this significant mechanical strength was combined with a brilliant fracture strain of 40%. Moreover, the 30 vol.% glassy reinforced composite possess hardness, compression yield strength, and fracture strain of 311(HV), 875 MPa, and 13%, respectively. All produced specimens reached near full density over 99% relative density, leading to a considerable combination of superior strength and ductility. Significantly, the SYS of powder thixoforging samples significantly increased from 89 kN m kg−1 for as cast condition to 290, 238, 220, and 199 kN m kg−1 for the monolithic and amorphous reinforced Al matrix composites of 12, 20 and 30 vol.%.
