Description
Summary:Titanium alloys are one of the most used materials in the medicine, aviation, and automotive industry. However, Ti alloys usually possess poor impact characteristics. One of the possible ways to overcome this problem is to develop graded materials with different mechanical characteristics in different layers. Herein, multilayer titanium composite comprising alternating Ti-6Al-4 V and Cp-Ti layers were produced by laser direct energy deposition. The impact toughness, layer microstructure, and mechanical properties have been investigated. Multilayer composites were heat treated using temperatures 800 ℃, 850 ℃, and 900 ℃. The influence of the sample orientation on the total energy of fracture, the energy of crack initiation, and the energy of crack propagation was analyzed. The results, which show a change in multilayer composite impact strength, are attributed to the influence on ductile Cp-Ti layers and fracture energy dissipation at the expense of crack deviation while crossing the interfaces. The results of mechanical tests show the intermediate strength and ductility of composite material in comparison with homogeneous materials of Ti-6Al-4 V and Cp-Ti. The developed material demonstrates a practical interest in the development of new types of materials with improved impact loads. Graphical Abstract
