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, TB, and the minimum amount of enthalpy relaxation leading to embrittlement, ΔHB are sensitive to the alloy composition. TB and ΔHB 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.
