Core-Shell Structured Particles Are Potential Reinforcement Agents For Metal Matrix Composites. In This Work, Aluminum Matrix Composites Reinforced With Core-Shell Structured Al35Ti15Cu10Mn20Cr20 High-Entropy Alloy (HEA) Particles Were Fabricated By Spark Plasma Sintering (SPS) And High-Temperature Diffusion Post-Treatment. Dynamic Compression Behavior And Adiabatic Shear Failure Mechanism In The Composites Were Investigated By Split Hopkinson Pressure Bar (SHPB), Scanning Electron Microscopy And Transmission Electron Microscopy. Results Showed That The Shell Thickness Of The Core-Shell Particles Ranged From 0.4 To 1.6 Μm, Which Were Formed By Thermal Diffusion Between HEA Core And Aluminum Alloy. The 30 Vol% (Al35Ti15Cu10Mn20Cr20)p/2024Al Composite Showed A High Compressive …
