【 摘 要 】

Technology of Severe Plastic Deformation (SPD) has emerged as a widely known procedure for the fabrication of ultrafine grained metals and alloys. Equal Channel Angular Pressing (ECAP) are one of methods of SPD has been developed for many applications; military devices, aerospace and automotive components. This paper examines recent developments related to the use powder of Aluminum alloys processed by consolidation-ECAP, for grain refinement; Al-5Mg, were compared by another type of Aluminum, which has also been researched. Characterization by mechanical, physical and microstructured. In the current study powder of material wrapped in copper capsule to be compressed and heated at a temperature of 400°C in hot press under the pressure of 450-500 MPa. Afterward the powder in solid condition was cooled in the air. The sample results of Aluminum by ECAP process then followed heat treatment with type Annealed, for heating at a temperature of 346°C for 1,5 continuing 415°C during 2 hours followed by heating at a temperature of 205-230°C for 4 hours. This paper describes the effect of heat treatment on the characteristics of the powder material on Al-5Mg are based on changes in the mechanical properties and microstructures.
