- •
Dissoltion of B in Mo under present condition can be negligible.
- •
Morphology and internal structure of powder particles change markedly with MA.
- •
After 40 h of milling, almost strain-free Moss with grain size of 6.5 nm forms.
- •
Mo lattice constant changes with the dissolution of Si and Zr atoms.
- •
Thermodynamic analysis shows preferred formation for Moss than amorphous phase.
