Interface microstructure morphology and formation evolution mechanism of Al-1060/Cu-T2 composites fabricated by explosive welding method

The paper presents the results of physical modelling of the plastic deformation of the Mg/Al bimetallic specimens using the Gleeble 3800 simulator. The plastic deformation of Mg/Al bimetal specimens characterized by the diameter to thickness ratio equal to 1 was tested in compression tests. The aim of this work was determination of the range of parameters as temperature and strain rate that mainly influence on the plastic deformation of Mg/Al bars during metal forming processes. The tests were carried out for temperature range from 300 to 400°C for different strain rate values. The stock was round 22.5 mm-diameter with an Al layer share of 28% Mg/Al bars that had been produced using the explosive welding method. Based on the analysis of the obtained testing results it has been found that one of the main process parameters influencing the plastic deformation the bimetal components is the initial stock temperature and strain rate values.

Detonating code, which is a flexible code with an explosive core, is normally used to transmit the ignition of explosives with high detonation velocity 6 km/s. Therefore it is difficult to use detonating code for the explosive welding of common metals toward the detonating direction since the welding velocity exceeds the sound velocity of metals. Hence, an explosive welding method using underwater shock wave generated by the detonation of detonating code was tried. In the present investigation, the details of the experimental setup and results are reported. And the welding conditions are discussed through numerical simulation. From these results it is observed that the above technique is suitable to weld thin metal plates with relatively less explosives.

Abstract Two Alloy N/316H bimetallic plates have been fabricated by explosive welding and rolling technologies respectively. Metallographic observations indicate that the rolled bimetallic plate has a straight bond interface, in which some cavities and precipitates exist. While the explosive welded plate shows a wavy bond interfaces. The interface thermal expansion mismatch between the two alloys were evaluated in the two plates at high temperature. Results show that the thermal expansion coefficient of 316H is larger than that of Alloy N. The thermal expansion coefficient of the substrate plates depends on the thickness ratio between Alloy N and 316H, which reaches the maximum when the ratio is 1:4.

Underwater Shock

In this report, we propose a new explosive welding method, and the welding is performed at employing underwater shock pressure produced by the underwater explosion of an explosive placed at one side almost vertical to the specimen to be welded. In order to prevent the reduction of the shock pressure with the distance away from explosive, a steel reflector is placed over the area of the specimen. The effects of the reflector are investigated based on the experimental results and the process is numerically analyzed results.

Aluminium and copper are two metals frequently used in the automotive and aerospace industries due to their properties of lightness and high conductivity. In this study, copper and aluminium plates were joined using the explosive welding method. The effects of the explosive ratio on the properties of the bonding interface were investigated. Results of the experimental studies showed that the bonding interface changed from a slightly wavy structure to a completely wavy structure as the explosive ratio was increased. It was found that due to the cold deformation resulting from the collision of the flyer and parent plates during the explosion, there was an increase in the hardness values near the bonding interface and on the outer surfaces of the plates. The increase in deformation hardening along with the increasing explosive ratios led to the reduced impact toughness of the composites. In the results of the tensile-shear and bending tests, no separation or fracturing was seen in the bonding interfaces at any of the explosive ratios. As a result, it was seen that the explosive welding method can be used in combining copper and aluminium materials.
