Apr 26, 2017· Porous magnesium/carbon nanofiber composites were produced using a powder metallurgic method to study the effect of ball milling time on their microstructure and hardness. Three ball milling times (240 min, 320 min, and 480 min) and two carbon nanofiber concentrations (% and 1%) were utilized in the production of these porous composites.

Carbide Ball Burrs. Use a ball or spherical shaped carbide burr to create concave cuts in your material or to shape and hollow out an area. Small carbide ball burrs from as tiny as in diameter are ideal for intricate carving projects. Many wood carvers, stone carvers and metal engravers use these carbide carving burrs in a hobby drill, micro motor or a high speed handpiece.
