چکیده
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 studied X-ray diffractometer (XRD), scanning electron microscope SEM, energy dispersive spectrometer (EDS), transmission (TEM), backscattering diffraction (EBSD) techniques. At this temperature, it has been observed that Al3Ti intermetallic compound is favored reaction results in dispersion original Al layer. A large number interfaces are formed between Al. deformed grains concentrated interface near Ti side. mechanical properties, including tensile compressive properties room analyzed. test indicate composite exhibited an average strength 258 MPa yield strain 9.86%. Compression show when a load perpendicular to layer applied, stress material 9.67% 474.09 MPa, respectively. Moreover, under parallel layer, fails due interfacial debonding.

Abstract: Composite specimens were prepared by dispersion of various amounts of nano-sized Al2O3 fillers in a monomer system containing 60% Bis-GMA and 40% TEGDMA. For comparative purposes, composite samples containing micrometer size Al2O3 fillers were also prepared following the same procedure. The mechanical properties of the light- cured samples were assessed by three-point flexural strengt...

TiC-Ti-Al mixed powders and TC4 titanium alloy foils were overlapped layer-by-layer in the graphite die. The TC4-based laminated composite sheets reinforced by Ti aluminide and carbide were successfully fabricated via spark plasma sintering (SPS) at 1100 °C with a well-bonded interface. The composite layers were mainly composed of TiAl, Ti₃Al, Ti₂AlC, and Ti₃AlC₂ phases. The carbides particles ...
