英文摘要: Abstract(#br)The influence of particle size on the mechanical behavior of B 4 Cp/6061Al composites prepared by powder metallurgy is investigated by combining the tensile test with finite element method (FEM) simulation. The experimental results show that increasing the particle size from 20 μm to 80 μm deteriorates the tensile property and work hardening rate of the B 4 Cp/6061Al composites. The actual three-dimensional (3D) microstructure obtained by synchrotron radiation X-ray computed microtomography (SR-μCT) is incorporated into finite element models to study the deformation behavior and internal damage of the composites. The matrix ductile damage, particle brittle failure criterion, and interface traction–separation law which are associated with particle sizes are employed to predict...
