Abstract
Copper and titanium plates were used in the studies. These plates were joined together by explosive welding using different amounts of explosives. The resulting composite plates were heat-treated at different temperatures. In microstructural studies, it was observed that the joints with the least rate of explosive used had an almost flat joint interface and as the explosive rate increased, a wavy structure was formed. Hardness values were found to increase as the rate of explosives increased, but hardness values decreased after heat treatment. It was observed that notch impact strength decreased with increasing explosive rate, but there was an increase in impact toughness values after heat treatment. Torsional testing of all specimens revealed no visible defects. Neutral salt spray tests showed that the copper surfaces of the composite plates corroded, but there was no corrosion on the titanium side.
期刊介绍：
