One step production of aluminium matrix composite powders by mechanical alloying

Mechanical alloying technique has been used to produce aluminium-based metal matrix composite powders. As base material, the aluminium alloy AA2014 was selected, and two different carbides (VC and TiC) were chosen as reinforcements. Elemental powders (Al, Mg, Si and Cu) and carbide powders were mixed together in a high energy horizontal ball mill (Zoz attritor), with a balls/load (in weight) ratio of 20/1 at 700 rpm for different times (5, 7 and...
