Effect of Texture on the Mechanical Properties and Ballistic Performance of an Extruded Al-6063 Rod

Abstract:

The present work describes the influence of texture and mechanical properties anisotropy on ballistic performance of an Aluminium-6063 extruded rod. It has been observed that the centre region of the extruded rod exhibits better strength, elongation and charpy impact values than the peripheral region. Texture of the extruded rod is measured from centre towards the periphery. A significantly variation in texture has been observed from the centre towards the periphery. Ballistic experiments are conducted on 80 mm thickness extruded samples by impacting them with 7.62 mm armour piercing projectile at 0° angle of impact at 840±15 m/s velocity. Results show that the centre of the extruded rod displays much improved ballistic performance than the periphery, which has been attributed to the strong {111} fibre texture present at the centre.
