    • Microstructure of heat-treated steel probed by positron annihilation 

      Al-Qaradawi, I. Y.; Abdel-Hady, E. E.; Megahed, H. (2001 , Conference Paper)
      Positron annihilation lifetime technique has been applied to study the microstructure change in steel after heat treatment. For this purpose, the specimens are heat treated in various manners; normalizing, annealing, ...

    • Positron annihilation lifetime study of pure and treated polyvinyl chloride 

      Al-Qaradawi, I. Y.; Abdel-Hady, E. E. ( scientific.net , 1997 , Article)
      Positron annihilation lifetime technique (PAL) has been applied to investigate the behavior of the free volume in pure and doped polyvinyl chloride (PVC) as a function of Pb concentration and temperature. It is noticed ...
