“…In this context, the concept of "moderated reactive sintering" was introduced by Harach and Vecchio in 2001, speci cally for the Ti-Al system [5]. Subsequent research on MIL composites has predominantly centered around the Ti-Al, Ni-Al, and Fe-Al systems [6][7][8][9][10][11][12][13][14][15]. Scholars have extensively studied the growth kinetics [1], damage evolution mechanism [16], elastic resistance [17], epitaxial toughening, and endogenous toughening mechanisms under high-temperature annealing conditions [1,18,19].…”

CoCrFeMnNi-based high-entropy/B2 structure aluminide-laminated composites were produced via the hot pressing diffusion sintering method at 1000 ℃. The results revealed that the aluminide structure layer based on the Al 13 (Cr, Mn, Fe, Co, Ni) 4 phase rst transforms into Al 8 (Cr, Mn, Fe, Co, Ni) 5 phases with a trigonal crystal structure and then gradually transitions into Al(Cr, Mn, Fe, Co, Ni) phases with a B2 cubic crystal structure under high-temperature annealing. During high-temperature annealing, the elements Ni, Co, and Fe exhibit higher diffusion rates and diffusion amounts in the aluminide layer. The transformation of the aluminide layer is mainly in uenced by the diffusion behavior of these elements.The absence of an oxidation interface barrier during high-temperature annealing results in multiple diffusion mechanisms, leading to the predominance of lattice diffusion and interface diffusion, which control the growth kinetic of the Al(Cr, Mn, Fe, Co, Ni) phase layer. The hardness indentation of the B2-Al(Cr, Mn, Fe, Co, Ni) phases, obtained by high-temperature annealing, shows no cracks and exhibits a multi-slip system characteristic of ductile aluminum compounds. This ductile behavior helps to reduce the deformation resistance in the hard and brittle layer and decreases the likelihood of delamination failure during plastic deformation. The bending strength of high-entropy/aluminide-layered (HAL) composite materials after high-temperature annealing reaches 1000 MPa, with the main energy dissipation modes being the plastic deformation of ductile layer and fracture of the hard and brittle layer. Dynamic impact failure forms mainly include plastic deformation and delamination, with impact strength and energy consumption reaching 2317 MPa and 4750 J/mm 3 , respectively. This study provides phase formation sequence and dynamic mechanical properties of High-entropy CoCrFeMnNi/B2 structure aluminide-laminated composites which proved to be a new type of composites with good impact resistance.

“…Therefore, metal laminate composites (MLCs) have been used, which consist of a reinforcing element (e.g., fibers, cermet) and a ductile matrix material (e.g., steel, aluminum, titanium, etc.) [20][21][22][23]. Additionally, NiAl can be used as the reinforcing element in MLCs [24,25].…”

“…Moreover, MIL composites can be produced through the SHS mode and explosive welding [30][31][32]. A common difficulty in the production of MIL composites is the significant differences in the physical and mechanical properties between the matrix material and the reinforcing element [21,23].…”

In this study, SHS was used to produce metal-intermetallic-ceramic laminate AlMg6-NiAl-TiC composite. The experiment conducted without a cylindrical powder pellet holder produced no joint between the NiAl and AlMg6 sheet. On the other hand, the experiment conducted inside a cylindrical powder pellet holder (CPPH) with a blind hole produced a joint. It was found that the AlMg6 sheet had a temperature of 400–550 °C across its entire thickness during SHS. The study of the microstructure and energy-dispersive analysis (EDS) of AlMg6-NiAl-TiC composite showed that it had five layers: (1) ceramic layer of 7-mm-thick TiC; (2) the upper diffusion layer that formed at the interface between NiAl and TiC consisted of TiC + NiAl; (3) an intermetallic layer, which consisted of 13-mm-thick NiAl; (4) the lower diffusion layer, which formed at the interface between NiAl and AlMg6; and (5) a layer of 4-mm-thick aluminum alloy AlMg6. The EDS showed that during the synthesis of NiAl and its interaction with the surface of the AlMg6 sheet, mixing of the components of the initial materials (NiAl, AlMg6) in the joint interface occurs. At the interface of NiAl and AlMg6, the microhardness was 790–870 HV, which indicates the presence of quenching structures in the melted zones.
