Deformation and Fracture Behavior of Particle-Reinforced Metal Matrix Composites and Coatings

Abstract This paper considers the deformation of Al/B 4 C and NiTi/TiC composites 6061T6 aluminum alloy with double-layer composite coatings reinforced by B TiC particles. Three- two-dimensional dynamic problems are solved numerically using Abaqus/Explicit. The thermomechanical behavior homogeneous matrices substrates is modeled an isotropic elastic-plastic formulation. nitinol matrix implies possibility a completely reversible elastic phase transition from austenite to martensite upon reaching critical equivalent strains. fracture particles in coating Huber criterion, taking into account stress mode type. study also examines effects volume fraction boron carbide NiTi on magnitude residual stresses strains after cooling under mechanical loads. influence arrangement layers strength material evaluated theoretically experimentally. results experiments qualitatively confirm simulation results.
