Structure of Mechanically Milled CNT-Reinforced Al-Alloy Nanocomposites

Mechanical milling of aluminum-based two Al-Si-Mg alloys were reinforced with multiwalled carbon nanotubes (CNTs) using a planetary ball mill, forming a nanocomposite structure. The milling took place for different timings of 1, 3, and 5 h to follow the dispersion and distribution of CNTs. The effects of concentration of CNTs (ranging from 0.5 to 2 wt%) and milling periods on the final microstructure of the composites were investigated. The...
