J-8: Mechanical and Microstructural Properties of Lightweight Laminates Manufactured by Explosive Welding: Marta Orlowska1; Piotr Bazarnik1; Zygmunt Szulc2; Malgorzata Lewandowska1; 1Warsaw University of Technology; 2ZTW Explomet GALKA, SZULC S.J.
The aim of this study was to produce laminated structures consisting of Ti, Mg and Al alloys plates cladded by the method of explosive welding. The microstructure and chemical composition of the explosively joined samples were investigated using SEM, EDX and STEM techniques. Mechanical properties were evaluated in the tensile testing and by microhardness analysis. The results demonstrated that explosive welding is an effective way to produce laminates from Ti, Mg and Al alloys plates. Laminated plates exhibit a good quality of bonding without voids and major delamination. In addition, it introduces large plastic deformation which induces the process of grain refinement. Microstructural analysis revealed changes in grain size, as well as changes in chemical composition and formation of new intermetallic phases. Tensile testing revealed that welds pose high mechanical strength.
