Modelling of Retention of a Diamond Particle in Matrices Based on Fe and Cu

This paper involves a numerical modelling of retention of a synthetic diamond particle in a metallic matrix. The analyzed sintered powders can be used as matrices for diamond composites. Sintered specimens obtained from two commercially available powder mixtures were studied. The model of a diamond particle embedded in a metallic matrix was created using Abaqus software. The aim of this report was to determine the influence of the mechanical and thermal parameters of the matrix materials on their retentive properties. The analysis indicated the mechanical parameters that are responsible for the retention of diamond particles in a matrix. These mechanical variables have been: the energy of particle, the elastic energy of matrix and the radius of plastic zone around particle.
