Abstract

Annealing-induced embrittlement of MgCuY amorphous ribbons was evaluated by bend testing and differential scanning calorimetry. Two embrittlement parameters, i.e., the onset temperature of embrittlement, T_B, and the minimum amount of enthalpy relaxation leading to embrittlement, ΔH_B are sensitive to the alloy composition. T_B and ΔH_B decrease with increasing Cu and Y content. It is presumed that relaxation-induced embrittlement was a consequence of the chemical short-range ordering between Mg and Cu or Y atoms.
