“…One of the solid-state joining techniques for obtaining reliable joints between dissimilar materials is explosive welding method (EXW). In this process, the energy comes from the explosion of explosive materials, and the pressure of the flyer plate is propelled toward the base plate (Ref 3,4). The main advantage of EXW is related to the ability of joining various shapes such as plate to plate (Ref 5) or tube to sleeve (Ref 4), and also it provides a high purity of the interface.…”

The manuscript presents a close examination of the titanium and aluminum platters manufactured by explosive welding method. In particular, the microstructure changes of the Al/Ti wavy shape interface after annealing at 773 and 903 K were studied. Three stable TiAl 3 , TiAl, and Ti 3 Al and a metastable TiAl 2 intermetallic phases have been formed in the state directly after explosive welding. The orientation map and TEM images obtained after explosive welding process showed very fine grains of aluminum mixed with intermetallics in the interface region between the peninsulas or islands. After annealing for 100 h the TiAl 3 continuous layer was obtained; however, the layer achieved at 903 K was much wider than that obtained at 773 K. An examination of the growth kinetics at 903 K revealed that incubation time was less than 5 min. After this period, the growth was solely governed by chemical reaction.

“…Although manufacturers have been using explosive energy for a long time however, explosives can be effective when the detonation energy is controlled [46][47][48][49]. Charge type and mass play an important role to control the detonation energy and impulse.…”

Forming sheet metals under blast loading or the explosive forming technique has many advantages for productions, but it is restricted due to its accuracy. This paper introduces a novel theoretical-empirical study for explosive sheet metal forming based on the simple plasticity principles. It provides a method of producing the sheet metal cone parts forming under blast loading, including an analytical model and experimental validation. Firstly, a theoretical-empirical model for cone forming based on underwater explosion employing the impulse method is developed. The model on the whole revealed the relationships among the geometrical parameters of forming a process that is very useful to predict the certain explosive mass for complete forming a cone part. Afterward, a series of experiments are conducted to validate the developed model and also for the required modification in the solution. Comparing the theoretical-empirical solution and experimental results, the ability of the presented model for estimation of the explosive mass is demonstrated. Experimental results show that the theoretical model matched the experiments well.
