Study of structure and properties of multilayer materials based on titanium alloys

Abstract

Abstracts The article presents the results of the study of the structure and properties of multilayer materials based on titanium alloys of various classes. The selection of initial compositions founded upon the approach previously tested in the development of multilayer materials based on steels is presented. The basic possibility of forming a laminar structure in titanium multilayer materials has been shown. Based on the analysis of the microstructure, especially the interlayer boundaries, the starting composition that is most suitable for this purpose has been proposed. In reliance upon the conducted tensile tests, it was established that multilayer materials based on titanium alloys have a complex of mechanical properties characteristic of this class of materials. The impact hardness tests performed, as well as the subsequent fractographic studies, allowed concluding about the effect of the condition of the interlayer boundary on the increase in the resistance of the material to dynamic fracture.
