Microstructure and mechanical properties of powder aluminium prepared by severe plastic deformation
Original language description
This paper describes properties of Al 99.7% produced by PM. Powder green were prepared via CIP. The prepared powder about size less than 400 ?m was compacted via conventional direct hot-extrusion (DE) at temperature of 450°C. Some extruded material was additionally processed by ECAP. The microstructural investigations were performed using OM and SEM equipped with EBSD unit. Examination of extruded powder compacts showed that during DE initial powder particles deformed into grains about size of 5 m. Thismaterial was further subjected to ECAP passes. The mechanical properties of this material were investigated using hardness measurements. In addition, creep tests in tension were conducted at temperature of 473 K and at the different applied stresses. The basic aim of this work is microstructure characterization and description of creep behaviour of powder aluminium prepared by DE. The further aim of this work is the evaluation of ECAP technique effect on mechanical properties of powder
