Purpose: The main goal of present study is to investigate the connection of the effect of the heat treatment with severe plastic deformation using the ECAP (equal channel angular pressing) process and by application of precipitation treatment. Design/methodology/approach: Precipitation treatment was used to increase workability and mechanical properties of the investigated alloy. Two periods of solution treatment time were applied. An aging behaviour of solution treated was studied The cold ECAP behaviour was determined using processing route Bc and the material was subjected to ECAP process up to six pressings. Findings: It was found that precipitation treatment increases the mechanical properties and workability of EN AC 51100 aluminium alloy. It was also found that the structure during severe plastic deformation is refined by interactions of shearing and slip bands. The application of ECAP method increases also mechanical properties of the tested alloy. Research limitations/implications: Current study presents the investigation results that was carried out on samples, not on final products. Practical implications: Current research is moving towards to develop high strength materials with increased mechanical properties and fine microstructure which are known as ultra-fine-grained materials, compared to well-known common with micrometer size of structure materials. Originality/value: This paper present the results of the structure investigation of AlMg3 alloy in initial state and after precipitation treatment using light and electron microscopy and includes the study of changes in mechanical properties in the tested alloy subjected to different types of treatments.
