Using Atomic Force Microscopy to Examine Flow Processes in Materials Processed by ECAP

摘要

Atomic force microscopy provides a useful tool for examining the flow processes occurring during the tensile testing of ultrafine-grained metals processed by equal-channel angular pressing (ECAP). This paper describes the results obtained from experiments conducted on a Zn-22% Al eutectoid alloy and high-purity (99.99%) aluminium. The results show these two materials behave in different ways in terms of the development of mesoscopic shear planes.
