Hydrogen interacting with shape memory alloys can be accompanied by several types phenomena related to the structure. those are: atomic rearrangements, hydrogen induced amorphisation, change of structural parameters of crystallised materials, suppression of the martensite type of phase transformation B2 -> B19, and hydrogen induced reversible and irreversible embrittlement.
