Mechanical Alloying: A Novel Technique to Synthesize

Mechanical alloying is a solid-state powder processing technique that involves repeated cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill. Originally developed about 50 years ago to produce oxide-dispersion-strengthened Ni- and Fe-based superalloys for aerospace and high temperature applications, it is now recognized as an important technique to synthesize.

Role of Ball Milling of Aluminum Powders in

A planetary ball mill (Torrey Hills- ND2L) with stainless steel cups (285 mL capacity) and balls (28 of 16 mm and 6 of 18 mm diameter) milled the powders in an argon (Ar) atmosphere. Ball to powder ratio was 30:1, and the mill speed was maintained at 200 RPM for durations of 0.25, 0.5, 1, 2, 4, 7, 11, and 19 hours. Particles Size Measurements.

The effect of ballmilling time and annealing

A mixture of 97 wt.% Ni and 3 wt.% SiC powder was prepared by varying the ball-milling time (8, 24, 36 and 48 h). The ball-milling process was followed by powder consolidation using spark plasma sintering (SPS) and rapid cooling to room temperature. The samples were then annealed at different temperatures (300 C, 700 C and 850 C).
