Mechanical properties of layered composites based on St3–Cu and St3–Ni

The test results of metal layered composites (MLC) based on St3–Cu and St3–Ni, depending on the number of volume fractions of original materials and heat treatment mode, are proposed. The experimental ultimate tensile strength values are compared with the ultimate tensile strength calculated according to the mixture rule. It is shown that the mechanical properties depend not only on the original properties of the MLC components but also significantly depend on technological factors. Based on the analysis performed, an assumption about the influence of the transition area of the joint boundaries on the mechanical properties of MLC is made. The obtained experimental data can be used to determine the heat treatment parameters, which will provide the required level of MLC mechanical properties.
