Abstract

The goal of the present study is development of high strength pure aluminum by Compression shearing method at room temperature. The powder shape and mean particle size of ultrafine-grained pure aluminum thin plate were changed using the compression shearing method at room temperature. The grain sizes of the ultrafine-grained pure aluminum thin plates were 0.5- 1.2 μm. The mechanical properties of the plates were measured, and the Vickers hardness and tensile strength were determined to be 56-90 HV and 175-320 MPa, respectively. Ultrafine-grained pure aluminum thin plates were developed that can have practically any breaking elongation and strength by discretionally changing the shape and mean particle size of the powder.
