چکیده انگلیسی
Structure, room temperature- and elevated temperature mechanical properties of the Al–5.7Cr–2.5Fe–1.3Ti alloy are studied in the presented paper. The alloy was prepared by the powder metallurgy including melt atomization into rapidly solidified powder followed by hot extrusion. The alloy shows a fine-grained structure (average grain size of 1 μm) and a relatively high tensile strength of 380 MPa. Variations in structure, hardness and tensile properties due to the long-term annealing at 400 °C/200 h are negligible, suggesting the excellent thermal stability of the alloy. Moreover, its tensile properties at 350 °C exceed the commercial Al–Si alloy commonly used in elevated temperature applications.
