Effect of Artificial Aging on Plane Anisotropy of 6063 Aluminium Alloy

الملخص EN

Most aluminum profiles’ production by deep-drawing and extrusion processes require certain degree of structural homogeneity because of the segregated second-phase particles in the as-cast structure.

Rolled texture and directionality in properties often give rise to excessive earring, breakout, and tears.

This study investigates the effect of heat treatment (artificial aging) on the anisotropic behavior of AA6063 alloy between rolling direction (0°) through 90° directions.

The results show significant reduction in property variability in the aged samples along the rolling direction 0°, and 90° directions compared with the as-cast samples.

This gave rise to improved % elongation, impact toughness, and substantial reduction (33.3%) in hardness.

These results are capable of achieving huge savings in die conditioning and replacement with improved quality and sale of deep-drawn AA6063 alloy profiles for sustained profitability.
