The influence of high energy-ball milling (HEBM) on corrosion and hardness age hardening aluminum alloys was investigated. Nanocrystalline (AA2024, AA6061 AA7075) were produced by HEBM pre-alloyed powder subsequent cold compaction under uniaxial pressure 3 GPa. Cyclic potentiodynamic polarization immersion tests conducted in 0.6 M NaCl solution which revealed significantly increased pitting pro...

This article presents the investigative work conducted on the fracture toughness and microstructure of Al6061-9% graphite particulate composites. The requisite specimens for the fracture toughness testing were compact tension ones prepared using stir casting technique. The Al6061-9% graphite particulate metal matrix composite has been heat treated in the underaged condition. It is observed from...

In computed tomography (CT), the nonlinear attenuation characteristics of polychromatic X-rays cause beam hardening artifacts in the reconstructed images. State-of-theart methods to correct the beam hardening effect are mostly single material precorrections (e.g. water-precorrection), which are far less efficient when more than one material is present in the field of measurement. The use of tho...
