Effect of Interfacial Layer Thickness on Mechanical Properties of HEA_p/Ti Matrix Composites

In order to study the influence of the interface layer thickness on the mechanical properties of HEA_p/Ti composites and the ring-breaking behavior of the composites during the tensile process,ABAQUS finite element analysis software was used to model single-particle and multi-particle models with different interface layer thicknesses.The simulation results show that as the thickness of the interfacial layer increases,the stress on the interfacial layer becomes larger. The tensile damage of composites is mainly matrix cracking and interface debonding.During the tensile process,the cracks of the composites first sprout at the interfacial layer,and with the increase of load,the cracks expand along the particles in the matrix.
