- Abstract
Metal-intermetallic layered (MIL) composites attract considerable attention due to their remarkable structural and ballistic performance. This study aimed to develop a Ti/al-based multilayered MIL material by adding ceramic powders, since they can improve the composite's impact resistance. To this end, an experiment was conducted which a stack of alternating Ti and al sheets bonded by hot pressing; Ti/al multilayers containing additional layers of Al2O3 and SiC powders were also produced. The samples obtained were examined using electron microscopy techniques. The clads' mechanical properties were investigated using a Charpy hammer. In the reaction zone, only one intermetallic phase occurred: the Al3Ti phase. The model with an additional Al2O3 layer showed the highest impact energy. none of the Ti/al clads broke during the Charpy impact test, a result proving their high ductility.
