Investigation of Structure, Properties and Deformation Mechanisms of Elevated Temperature Al Alloys with High Specific Properties
Abstract
The present project was devoted to the investigation of structure and mechanical properties of high-strength aluminum alloys especially alloys for elevated temperatures. High-strength aluminum alloys can have strengths approximately 50 times higher than the strength of unalloyed aluminum. Such a strong increase of the alloy strength is a unique case in the science of metallic materials and is a consequence of a tremendous number of theoretical and experimental works. For this reason a further increase of the level of mechanical properties of aluminum alloys is possible using new ideas and technologies. Just this approach was used for all six tasks of the present project. Investigation of mechanical properties was carried out by tension and bending test in various temperature ranges. Structural investigation were performed by X-ray diffraction technique TEM, SEM, OM, DSC analysis and by local X-ray spectral analysis. Correlation of processing chemical composition structure and mechanical properties was investigated for obtained high-strength aluminum alloys. The mechanisms of alloy deformation and fracture in most strong condition were revealed.
