Characteristics of high temperature creep in pure aluminium processed by equal-channel angular pressing

Characteristics of high temperature creep in pure aluminium processed by equal-channel angular pressing
Characteristics of high temperature creep in pure aluminium processed by equal-channel angular pressing
High purity aluminum was processed by equal-channel angular pressing (ECAP) to reduce the grain size to ~1.3 µm. Tensile specimens were cut from the as-pressed billets and these specimens were tested under conditions of high temperature creep. The results show excellent creep properties with a well-defined region of steady-state flow. The flow behavior is analyzed by comparing the creep data with the predicted behavior for different fundamental creep mechanisms and by plotting a deformation mechanism map to provide a visual representation of the creep properties

Abstract

High purity aluminum was processed by equal-channel angular pressing (ECAP) to reduce the grain size to ~1.3 µm. Tensile specimens were cut from the as-pressed billets and these specimens were tested under conditions of high temperature creep. The results show excellent creep properties with a well-defined region of steady-state flow. The flow behavior is analyzed by comparing the creep data with the predicted behavior for different fundamental creep mechanisms and by plotting a deformation mechanism map to provide a visual representation of the creep properties
