Attenuation of Disturbances Using Packed Bed of Nanoparticles

Asif M., Ali S.S., Hameed B.H., King Saud University, SA

The attenuation of disturbances and shocks is quite important as well as challenging task in a variety of situations. In the present work, the attenuation of disturbance through a packed bed of ultrafine nano-powder that [...]

Manufacturing of thermally stable nanocrystalline aluminum alloys and studying their corrosion behavior in Arabian Gulf seawater

Sherif E.M., King Saud University, SA

The as-received metal powders were used to synthesis bulk nanocrystalline Al; Al-10%Cu; and Al-10%Cu-5%Ti alloys using mechanical alloying and high frequency induction heat sintering (HFIHS). The corrosion behavior of these materials in natural Arabian Gulf [...]

Utilization of Industrial Waste as a Composite Cementing Materials

Khan M.I., King Saud University, SA

The deterioration in concrete structures exposed to harsh environments has become a matter of global concern. The requirement for high durability in concrete structures cannot be easily achieved using ordinary portland cement. Therefore, new materials [...]
