The purpose of this study is to produce composite plates by explosive cladding process. This is a process in which the controlled energy of explosives is used to create a metallic bond between two similar or dissimilar materials. The welding conditions were tailored through parallel geometry route by using different explosive ratios to produce both wavy and straight interfaces. In this investigation, a two-pronged study was adopted to establish the conditions required for producing successful solid state welding: (a) Analytical calculations to determine the weldability window; (b) Metallurgical investigations of experiments carried out under different conditions. The required parameters in the experiments were selected through numerical simulations. The analytical calculations confirm the experimental results. Optical microscopy studies show that a transition from a smooth to wavy interface occurs with increase in explosive ratio. Scanning electron microscopy studies show the formation of intermetallic layer in the interface.

In this study, the microstructure evolutions of the interface of the explosively welded cp- Ti/AISI 304 S.S composites due to heat treatment are presented. The composites were subjected to heat treatment process at various ranges of 650-950°C in argon atmosphere for 1hr. The investigations were carried out by using optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and X-ray diffraction (XRD). The results reveal the presence of reaction layers in the interface and show that heat treatments cause to form different intermetallic phases at the interface. In addition, it is found that the width of the interfacial layer increases with temperature. Fractographical studies of the lug-shear test samples show the formation of river patterns and kirkendal pore structures on the Ti-side of the interface.
