On the Possibility of Using Amorphous Metals in High Radiation Environments

Source

Amorphous metals (AM) are promising materials for use in high dose irradiation environments due to their often higher irradiation resistance compared to crystalline metals, at least regarding dpa-type damage. A high thermal stability and a sufficient mechanical stiffness is required additionally for the envisaged application as a stationary proton beam window of the German spallation neutron source. Potentially suitable AM's are identified by theoretical considerations. The possibility of using known, but specially prepared AM's is discussed in detail. Concerning the gas-embrittlement, for the first time a He-bulk implantation has been performed on the AM Ni78Si8B14 at room temperature and 300 °C up to a He-concentration of 1.000 appm. A clear He-influence is not observed on the ductility losses, which can be attributed to a temper embrittlement. TEM investigations reveal no discernable He-bubbles both for as-implanted and subsequently annealed specimens up to the crystallization temperature.
