Mechanical alloying of brittle materials

Microstructural evolution characterization of Fe–Nb–B ternary systems processed by ball milling

“…The evolution of Nb during ball milling is typical for ductile materials [3,21], developing long crystals with a large surface, which facilitates the incorporation of this element into the Fe nanocrystalline matrix forming a supersaturated α-Fe(Nb) solid solution. The present results do not disagree with the preferential partitioning of Nb to intercrystalline region derived from Mössbauer results [15].…”

Microstructural Evolution, Thermodynamics and Kinetics of Mo-Tm₂O₃ Powder Mixtures during Ball Milling

“…Davis reported that the maximum temperature rise during ball milling was approximately 300 °C in a Fe-1.2wt% C steel system [31]. Tonejc's research showed that the local rise in temperature was at least 570 °C in a Ga-Sb alloy system [32].…”

Improving Hardness and Toughness of Boride Composites Based on AIMgB₁₄

“…It is termed a vibratory/oscillatory mill because the milling vial travels rapidly along a "figure-eight" path designed to induce more random collisions and eliminate dead spots within the vial. It is also among the highest energy ball mills, producing estimated media speeds of 6-18 m/s which are more than sufficient for most MA experiments, and thus it is a popular mill in research [71,[86][87]. The major drawbacks of the Spex 8000 are the considerable wear rate of media and the small sample size of ~2 cm 3 (suitable for laboratory experiments but inadequate for commercial use) .…”
