Excellent work-hardening in ZrCu/NiNb amorphous/amorphous nanolaminates

Work-hardening behavior could be rarely observed in amorphous alloys during plastic deformation because the dilation and softening effect often occur in shear bands. Here, we proposed a novel mechanism to realize an excellent work-hardening rate (R=dσdε) in ZrCu/NiNb amorphous/amorphous nanolaminates (A/ANLs), which is investigated by in-situ uniaxial micro-pillar compression tests. The work-hardening rate value (25.24 GPa) obtained in ZrCu/NiNb...
