- Abstract
- In this work, the microstructure and mechanical properties of multilayer composite materials consisting of alternating layers of a cermet composite powder based on molybdenum and layers of metal foils of molybdenum, tungsten and tantalum were studied. The study was aimed at determining the strength characteristics of a layered composite material with a reinforcing layer based on a refractory metal and studying the material's fracture pattern after strength studies. As a result of studying the strength characteristics, it was found that a layered composite material: reinforced with tantalum layers has a bending strength of 1000 MPa and a density of 9.7 g/cm3, material reinforced with molybdenum layers has a bending strength of 760 MPa and a density of 8.9 g/cm3, material with tungsten layers has a bending strength of 839 MPa and density 11.4 g/cm3. Investigation of the microstructure of the laminated material after the bending test and after thermal treatment at 1600 оC showed that material delamination does not occur either after bending tests or after heat treatment, which indicates on the formation of strong metal bonds during compaction of the layered structure.
