| 英文摘要 | The influence of particle size on the mechanical behavior of B4Cp/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 mu m to 80 mu m deteriorates the tensile property and work hardening rate of the B4Cp/6061Al composites. The actual three-dimensional (3D) microstructure obtained by synchrotron radiation X-ray computed microtomography (SR-mu CT) 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 the tensile properties. The deformation behavior and damage mechanism in the B4Cp/6061Al composites are revealed by analyzing the stress and strain distributions. Furthermore, stress concentration factor is considered to evaluate the load-bearing capability of the composites reinforced by various particle sizes. This work provides a reference for studying the mechanical behavior of heterogeneous microstructural materials via actual microstructure-based modeling. |
