hardness ball milling

2017/04/26 · 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 nbspmin 320 nbspmin and 480 nbspmin) and two carbon nanofiber concentrations (0.05 and 1 ) were utilized in the production of these porous composites. The increase of ball milling
