Abstract

The influence of γ-irradiation on brittleness of the amorphous alloy Fe78Si9B13 annealed at different temperatures has been studied. It is shown that the brittleness temperature of the γ- irradiated alloy rises by about 30℃. The measurements of Mossbauer effect

X-ray diffraction

and positron annihilation indicate that this is attributed to the slowdown of the alloy’s structure relaxation due to γ-irradiation before the crystallization.
