“…The direct growth of quasicrystals was reported in multilayer Al-Cu-Fe thin films after subsequent heat treatment [13]. Successful application of Al60Cu28Fe12 quasicrystalline and film coating obtained through three-electrode ionplasma sputtering of assembled targets was reported, and this coating contained a quasi-crystalline 𝑖-phase that was stable up to 723K [14]. The formation of the Al62.5Cu25Fe12.5 quasicrystalline phase was achieved by the Al-Cu system at temperatures relatively higher than 500 (T>500°C).…”

Different industries, including aerospace, marine, and automotive, widely use titanium alloys such as Ti-6Al-4V. Although, this alloy has excellent properties; it is highly susceptible to corrosion and has low thermal stability and tribological characteristics, limiting its application. In this research, after preparing the Al62.5Cu25Fe12.5 quasi-crystalline (QC) powder mixture and appropriate target, the magnetron sputtering method was employed to deposit the QC coating on the Ti-6Al-4V substrate. The powder mixture and AlCuFe thin films were annealed at 700 0 C for 2 h. The scanning electron microscope (SEM) analysis and X-ray diffraction (XRD) methods were used to investigate the microstructure and morphology of mixed powders and Al-Cu-Fe QC coatings. NaCl solution (3.5 wt.%) was utilized to conduct the electrochemical measurements. Al-Cu-Fe thin layer deposited on the Ti-6Al-4V alloy surface without any cracks. The XRD patterns related to the annealed powders and the coating after heat treatment indicated the presence of Cu3Al, AlFe3, and quasi-crystalline ternary phases of Al65Cu20Fe15, Al3Fe, AlTi2, and Al65Cu20Fe15 phases, respectively. Based on the polarization test results, the annealed coating at 700°C showed better electrochemical behavior than the Ti-6Al-4V substrate.

“…In addition, it is necessary to reduce the cost of filler materials and improve the hardfacing process efficiency In this connection, Fe–C–B system alloys being highly resistant to abrasive wear and having relatively low cost, become more widely spread [ 59 , 60 ]. Today, there are numerous investigations into simple ternary alloys of the Fe–C–B system [ [61] , [62] , [63] , [64] ], as well as additionally alloyed with a carbide-forming element [ 25 , [65] , [66] , [67] ] such as Cr [ 41 , [68] , [69] , [70] ], V, Nb, Mo [ 71 , 72 ], Ti [ 47 , 73 ], ferrite forming element (Al, Si) [ 58 , 73 ] and austenite forming element [ 74 ] (Cu [ 75 , 76 ], Ni, Mn). Boron can form the following compounds in these alloys: iron monoboride FeВ, hemioboride Fe 2 B, Fe 3 (B,C) and cubic boron carbide Fe 23 (C,B) 6 .…”

“…To fabricate MMCs with enhanced properties, the processing technique must ensure a high volume fraction of reinforcement, its uniform distribution and acceptable adhesion between the matrix and the reinforcing phase without unwanted interfacial reactions that degrade the mechanical properties. Many processing tech-niques have been developed to produce MMCs employing a variety of binder and reinforcement combinations [6][7][8][9][10][11][12]. Among these, a spontaneous infiltration process is widely used for making MMCs with a high volume fraction of reinforcements which offers many more advantages compared to those of other conventional manufacturing processes [13][14][15][16].…”

The spontaneous infiltration method for fabricating composites was used, in which molten Cu–Ni–Mn–Fe binders penetrated W–C filler particles due to capillary forces. The metal matrix composites thus obtained were characterized for phase composition, microstructure, porosity and microhardness. All composites were studied in their as-prepared condition with further annealing at 900°С for 60 and 750 h. It was shown that the mechanism based on the dissolution/diffusion bonding of the particulate/matrix interface was in agreement with the results of this study. The interfacial reactions provided a driving force for wetting but did not give rise to unwanted phases that could degrade the properties of the composite materials. From the EDX measurements it was concluded that mainly Fe atoms diffused from the Cu–Ni–Mn–Fe binders into the WC phase of the eutectic (WC+W2C) filler. Dissolution of this phase resulted in the appearance of W2C layer at the interface. Annealing at 900°С significantly promoted the interfacial reaction especially during the first 60 h of heat treatment. The degree of the reaction between the molten Cu–Ni–Mn–Fe alloys and W–C particulate could be limited by controlling the iron content of the binders to obtain an optimal interface.
