摘要：

Aluminium 7075 is frequently used in aircraft structures. Aluminium metal-matrix composites with 0 TiC (w/%), 8 % TiC and 16 % TiC were produced using the powder-metallurgy technique. Metallurgical studies, such as X-ray diffraction (XRD) and scanning electron microscopy (SEM). were made to confirm the occurrence of reinforcements. A cold-upset test was conducted on the synthesized composites and different stress parameters were calculated to study the forming behaviour of the produced composite in the tri-axial stress-state condition. The values of the stresses were found to be highest for the aluminium composite reinforced with AA7075 + 16 % TiC.
