The temperature influence on the microscopic characteristics of plastic deformation morphologies in nanocrystalline Ni-Fe investigated with atomic force microscopy

摘要

The microscopic characteristics of compressive deformation morphologies in nanocrystalline Ni-20Fe alloy were investigated using atomic force microscopy. The results indicate that in room temperature compression, nanograin alignments and displacements are the observed main deformation events. Compression at 600 deg C leads to development of sub-microscopic deformation lines formed through gliding in-between nanograin-clusters.
