On the microstructure, texture and mechanical properties through heat treatment in Al-CuO nanocomposite fabricated by Accumulative Roll Bonding (ARB)

This study focuses on the Al-0.5 vol% CuO composite creation. Therefore, the researchers used the accumulative roll bonding (ARB) process to establish the Al-0.5 vol% CuO composites. The composites were created in three ARB methods; the usual way, with rapid annealing and preheating between ARB cycles. Heat treatment was adjusted at 190 degrees C and lasted for 5 min. This study used a small amount of reinforcing particles, which resulted in the absence of any porosity in the composite. The ARB process resulted in the average size of the created composite grain in the usual way, with the rapid annealing and preheating to be 219.19 nm, 306.54 nm, and 355.65 nm, respectively. The composite creation through the ARB process increased the tensile strength by more than 2.5 times. The ARB with preheating, causes dynamic recovery, dramatically reducing the metal matrix hardness. In this way, the particles were swept instead of getting spread. Therefore, the tensile strength and elongation of the sample were lowered.

Automated summary
