• Nanocrystalline TiAl powders synthesized by highenergy ...

    Highenergy ball milling was employed to produce nanocrystalline TiAl powders. As sticking of the powders can be sufficiently severe to result in a near zero yield, emphasis was placed on varying milling conditions so as to increase the yield, while avoiding contamination of the powders.

  • wet ball milling process 2ccao

    Highenergy ball milling is a type of mechanical grinding of materials. This process can be conducted in a dry (without solvents) or wet (with solvents) fashion. Laboratoryscale ball milling (5−100 mL scale) is a batch process, whereas industrial ball mills can be operated in a continuous mode, thus offering a very high synthesis throughput.

    · After 30 h of ball milling with the addition of CuO, the two elements (Mo and Nb) show different phase evolution processes and final states probably due to their different chemical properties. In order to make a better observation of alloying process during ball milling after the addition of CuO, we performed a twostep ball milling procedure.

    Occasionally, metal powders are milled in a liquid medium also named as wet milling. However, if there is no liquid used during the milling process it is called dry milling [22, 23]. During wet milling, due to the low efficiency such as retarding crystallite refinement attributes to the decrease of the ball's impact force on powders [17, 18, 23].
