Stability of intermetallic compounds under extreme actions

Conclusions  

1.	The change in the crystal structure of the studied intermetallic compounds observed under different extreme actions (quenching from liquid state, ion irradiation, treatment in a ball mill) can be described as a change in the packing of close-packed layers (the formation of packing defects and polytypes in μ-, λ-, and ε-phases) or a change in the atomic ordering (ε, σ, Cr3Si type, andH-phase).
2.	The relative stability of the crystalline state of intermetallic phases under high-energy actions is independent of the type of the action and is determined by the crystallochemical nature of the phase.
