The magnetic properties of metastable Co 3 C synthesized via reactive ball milling in nitrogen and argon are reported.. Dissolved nitrogen is effective in increasing transformation rate, coercivity, and decomposition temperature of Co 3 C.. A maximum coercivity value of 106 kA/m (1.34 kOe) is obtained in a 473 K annealed Co 3 C sample.

Commercial powders of pure magnesium were processed by high-energy ball milling. The microstructural and morphological evolution of the powders was studied using scanning electron microscopy (SEM), energy dispersive spectrometry (EDX) and X-ray diffraction (XRD). From the results obtained, it was determined that the ball size is the most influential milling parameter.

Transcribed image text: The ball mill (detailed in Figure 1 below) comprises of large drum (1m in diameter and 1.3m long) that is partially filled with rock and steel balls, and as the drum rotates the steel balls impact the rock to grind it down into smaller pieces. The mill is situated in a remote location, where the ambient temperature can be as high as 50°C, and in the direct sunlight the ...
