Abstract:
Nanostructured metals are of interest because of their unique physical and mechanical properties of high strength, creep resistance and aims towards potential use in a variety of applications. Ball milling at cryogenic temperatures (Cryo-milling) is more effective in this capacity due to the low temperature by slow-recovery, cold welding and minimizing diffusion distances between powder particles. Its low energy ball milling process produces nanostructures in metal powders through severe repetitive deformation. Powder with a particle size less than 40Aμm was mechanically milled in liquid nitrogen environment for 3 to10 h, and stainless steel balls with a diameter of 6.4 mm were used as the grinding media with the ball-to-powder mass ratio of 30:1. Outcome powder is consolidated in FSW machine on the principle of High Shear Powder Consolidation technique. The advantages in newly designed Cryo-milling setup are a setting of simple parameters and there is uniformity in the outcome powder.
