| Research Abstract |
We investigate the plastic deformation processes of amorphous alloys and tried to reveal the mechanism of the shear fracture at atomic scale. The plan was the atomic scale observation of structural changes in amorphous nanowires under tensile stress with transmission electron microscopy (TEM). To accomplish this, we do need the preparation of the nanowire by cutting and depositing in the dual beam SEM/FIB machine.However, the Great East Japan Earthquake on March 11, 2012 caused the damage to both TEM and SEM/FIM machines and delayed the experimental schedule of the nanomechanical tests. Therefore, we have switched over to focus the mass production of the amorphous alloy nanowires and have succeeded to invent the way to produce nanowires from the variety of amorphous alloys such as Pd, Zr, Fe, and Co based.
