In this article, the amorphization temperatures and particle sizes of the pseudo-binary Er(Co[sub 1[minus]x]Fe[sub x])[sub 2] compounds are investigated as a function of the alloy composition, and related with hydrogen content and elastic modulus. Previously, it was reported that the ternary Er-Co-Fe system formed a homogeneous single phase with C15 cubic structure over the whole concentration range and absorbed a large amount of hydrogen at ambient conditions. Hydrogen concentration in Er-Co-Fe system had a maximum at the composition of x = 0.6, Er(Co[sub 0.4]Fe[sub 0.6])[sub 2]. Thus, the possibility exists of hydrogen-induced amorphization, and also of an effect of hydrogen concentration on the amorphization behavior.
