In this study, austenitic stainless steel (AISI 316L) and S235JR plates were joined via explosion welding method, which is one of solid state welding methods, and by using two different explosive rates (R=1.5-2). The developed composite materials microstructure was evaluated in order to see changes occurring in the joint interfaces and the hardness, and fatigue tests were carried out to determine their mechanical properties. As a result of the experiment, the fluctuation occurring in the joint interface of samples was observed to be very low for low explosive rate, On the other hand, it was determined that in the sample in which higher explosive rate was used the lengths and amplitudes of waves increased in the joint interface. An increase was determined in hardness of materials forming the composite due to deformation occurring as a result of increase of explosive rate. In fatigue tests applied to composite materials, a decrease was found in fatigue life of composites as a result of increase of explosive rate.
