Effect of Al2O3 Particles on Bond Strength in the Roll Bonding Process of Al-1050 Bi-Layers
- 48 Downloads
Aluminum alloy 1050 strips are roll-bonded with interlayer Al2O3 particles. The effect of rolling parameters on the bond strength, such as the content of Al2O3 particles, plastic deformation, and rolling temperature are investigated by peel test. It is established that higher bond strength can be obtained by increasing the rolling temperature, reducing the thickness, and decreasing the alumina content. The peeling surface of samples versus alumina content is characterized by scanning electron microscopy.
