Influence of Explosive Ratio on Morphological and Structural Properties of Ti/Al Clads [PDF]

Metals, 2019
The current work focuses on the effect of explosive ratio R on the comprehensive properties of Ti/Al clads manufactured via explosive welding. The lower and upper limits of explosive ratio, namely R1 and R2, were determined according to the R⁻δ
