Experimental Investigations on Explosive Cladding of Cp-Titanium / AISI 304 Stainless Steel

Abstract:

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.
