“…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.

“…These composites are prepared using various intermetallic compound systems such as Fe-Al [2], Ti-Al [3], and Ni-Al [4]. Among these systems, Ti-Al 3 Ti MIL composites exhibit low density, high modulus of elasticity, and exceptional high-temperature properties, making them promising materials for hightemperature-resistant structural applications [5][6][7][8]. In 2001, Vecchio [9] created MIL-layered composites using Ti-Al plates stacked on top of each other in an air environment and reacted through sintering.…”

Novel HEAp-Ti/Al laminated composites embedded with particles of the high-entropy alloy Al0.5CoCrFeNi (HEA) were fabricated by vacuum hot-press sintering at 730 °C. The phase composition and microstructure of the composites were studied with X-ray diffractometer (XRD), scanning electron microscope SEM, energy dispersive spectrometer (EDS), transmission electron microscope (TEM), and electron backscattering diffraction (EBSD) techniques. At this temperature, it has been observed that Al3Ti intermetallic compound is the favored phase and the reaction results in the dispersion of Al3Ti in the original Al layer. A large number of interfaces are formed between Al3Ti and Al. The deformed Al3Ti grains are concentrated in the interface near the Ti side. The mechanical properties, including tensile and compressive properties at room temperature, were analyzed. The tensile test results indicate that the composite exhibited an average tensile strength of 258 MPa and an average yield strain of 9.86%. Compression test results show that when a load perpendicular to the layer is applied, the yield strain and yield stress of the material are 9.67% and 474.09 MPa, respectively. Moreover, under a load parallel to the layer, the material fails due to interfacial debonding.
