Effect of reversible structural relaxation on diffusion in a ZrTiCuNiBe bulk glass

Diffusion coefficients of B and Fe were measured in the Zr 46.8Ti 8.2Cu 7.5Ni 10Be 27.5 bulk glass which was relaxed at 553 K for up to nine months. While above 600 K the diffusion coefficients in the relaxed and as-cast glass were equal, at and below 553 K the diffusion coefficients in the relaxed...

Zusammenfassung:	Diffusion coefficients of B and Fe were measured in the Zr 46.8Ti 8.2Cu 7.5Ni 10Be 27.5 bulk glass which was relaxed at 553 K for up to nine months. While above 600 K the diffusion coefficients in the relaxed and as-cast glass were equal, at and below 553 K the diffusion coefficients in the relaxed glass were significantly lower than in the as-cast glass.
