The present work pertains to the study of microstructure and mechanical properties of explosively cladded commercially pure titanium (cpTi) with austenitic stainless steel (SS 304L) subjected to varied process parameters, viz., loading ratios (mass of explosive or mass of flyer plate) and preset angles. The microstructural study reveals the transformation from straight to wavy interface while increasing loading ratios. Vickers hardness increases with loading ratios, and the maximum hardness is witnessed in the closer proximity of collision interface. Ram tensile and shear strength of explosive claddings are higher than that of parent plates. While the base plate fails in impact test, the flyer plate is deformed, indicating good impact strength. Increased mass of claddings, due to oxide formation, is witnessed in corrosion tests, which confirms the superiority of explosive claddings in corrosive environment. Triaxial weldability window, an analytical estimation for Ti−SS 304L explosive claddings, is developed and correlated.
