- Abstract
Herein, the interface characterization and tensile properties of TA1/Q235 composite fabricated by explosive welding are investigated in the temperature range 650–950 °C. The explosive‐welded TA1/Q235 composite presents the periodic wavy bonding interface with both the vortex and solid–solid bonding regions. Some defects, including cavities, cracks, and brittle intermetallic compounds, are located in the melted zone of the interface wave. The compound layer comprises FeTi and Fe2Ti, with a thickness of 25 μm. In terms of high‐temperature tensile tests, the elongation of the TA1/Q235 composite exhibits a tendency of first increasing and then decreasing with increasing tensile temperature. And the elongation reaches the peak value of 95% at 800 °C. The tensile strength basically decreases with increasing temperature, except for a slight increase at 900 °C. The failure of the TA1/Q235 composite is affected by both the discontinuous compound and the continuous compound layers. With the increase in tensile temperature, a continuous compound layer with a certain thickness dominates the failure of the TA1/Q235 composite.
