A high-energy ball milling technique was employed to prepare ultrafine cemented carbide nanocomposite powders with compositions (wt.%) of 93WC/7-xCo/xZrO2-2mol% Y2O3 powders (x=0, 1, 2, 3, 4, 5, 6, 7 wt%). The nanocomposite powders obtained after [...]

Effect of the Consolidation Techniques on the Mechanical Properties of Nanocrystalline Ti55C45 Powders Prepared by Mechanically Induced Self-Propagating Reaction

Sherif El-Eskandarany M., Al-Hazza A., Al-Hajji L., Shaban E., Al-Rowayeh A., Kuwait Institute for Scientific Research, KISR, KW

A single phase of NaCl-type TiC was obtained after 5 h of ball milling. To decrease the powder and grain sizes, the synthesized material was subjected to further ball milling time. The powders obtained after [...]
