摘要：

In order to obtain titanium and aluminum composites with excellent performance and master the energy flow form when interlayer is used in explosive welding technology, energy calculation, SPH numerical simulation and experiment were used to conduct a comparative study of TA2/5083 and TA2/1060/5083 in this paper. Under the experiment conditions, TA2/1060, 1060/5083, TA2/5083 interface welding energy are respectively 547.17 MJ, 1178.86 MJ and 1455.5 MJ.The use of 1060 interlayer improves energy utilization efficiency by 14%. Numerical simulations and experiments showed that there was a continuous melting zone and a non-welded zone at the interface without interlayer. After the interlayer was used, the TA2/1060 interface was flat and the 1060/5083 interface showed a wave. There was no brittle intermetallic compound at the titanium-aluminum composite interface. The use of interlayer reduces the welding energy of a single interface, and the constructed theoretical equation showed that the interface energy can be accurately designed by adjusting parameters of explosives, flyer plates, interlayers and base plates. The use of pure aluminum interlayer is an effective means to improve titanium-aluminum explosive welding conditions (c) 2020 The Authors. Published by Elsevier Ltd.
