Outline of Final Research Achievements |
Temperature memory effect of stress releasing in amorphous ribbons was studied by transmission XRD, thermal expansion, and nano-indentation. The amount of quenched strain becomes large with increasing annealing temperature. The deviation to higher temperature occurs with increasing the holding time in the first stage, while the opposite happens with decreasing the holding time. Those results can be explained by newly proposed model with hetero-structure of viscousity in the amorphous ribbons. The predicted size of those heterostructure can be relatively large, in the scale from a few 10 to a few 100 nm, suggested by nano-dentation results.
