Abstract: (2651 Views)

Aluminum base composites are manufactured in a variety of methods, such as mixing in liquid state, mechanical alloying and so on. Explosive welding is one of the modern ways of producing Aluminum base composite. Explosive welding is used for excellent bonding of similar and dissimilar materials with a wide variety of thicknesses, area dimensions and different thermal and mechanical properties. In this study, Aluminum plates were reinforced by steel wires by explosive welding. The steel wires are placed between two Aluminum plates and joint between plates and reinforces were made by explosive welding process. The quality and morphology of the interface depend on stand off, the geometry of the welded plates, the properties of the metals, etc. In this paper, the appropriate parameters were determined using the numerical simulation and drawing of weldability window and layout of explosive welding was designed. The produced parts were examined by optical microscope. The simulation results showed that in the constant stand off by increasing the explosive ratio in constand stand off, velocities collision and also dynamic collision angle increased. The metallography results showed that the composite obtained excellent bonding quality of interface without void and fracture.
