The silicon carbide particles have a polygonal or angular shape. The average particle size of SiC particles was 36.4 µm. Mechanical milling of the initial SiC particles was performed by a Fritsch ball mill (Model Pulverisette 7) with tungsten carbide vial with the volume of 80 ml and balls with the diameter of 10 mm in argon atmosphere.

In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed. • Optimum diameter of the mill for grinding powders is about 250 mm Ball Mill

The Planetary Mill PULVERISETTE 5 premium line provides two stations of grinding bowls with 500 ml volume (largest capacity on the market). Each grinding bowl can be filled 1/3 part of the volume (± 170 gr sample). So, if we use two grinding bowls, the optimum capacity is about 170 x 2 = 340 g per milling process. 3.

The Cantor high-entropy alloy (HEA) of CrMnFeCoNi is a solid solution with a face-centered cubic structure. While plastic deformation in this alloy is usually dominated by dislocation slip and deformation twinning, our in situ straining transmission electron microscopy (TEM) experiments reveal a crystalline-to-amorphous phase transformation in an ultrafine-grained Cantor alloy.
