Summary: Mechanical alloying with high-energy ball milling is used to prepare high-entropy alloy (HEA) matrix nanocomposite powders with tungsten carbide (WC) particles. The repeated plastic deformation, fracture, and cold welding of the HEA powder result in the transformation from a body-centered cubic (BCC) phase to a face-centered cubic (FCC) phase and the gradual dispersion of WC microfine powder in the HEA matrix. The final product is a biphasic HEA-matrix WC nanocomposite spherical powder.

Summary: The computational framework utilizes novel differential effective medium approximation and mean-field homogenization to design high-performance filler-laden polymer thermal interface materials. The design strategy allows for handling non-dilute filler concentration and tailoring effective thermal conductivity by varying filler attributes within the constraints of the shear modulus. Potential polymers and fillers are considered, and high-density polyethylene and thermoplastic polyurethane with ceramic fillers exhibit high thermal conductivity without compromising compliance. The model validates that manipulating filler alignment and aspect ratio contributes significantly to heat-conducting networks in composites for ultra-high thermal conductivity.
