Mechanical Properties and Thermal Stability of Al-Si-X Based Alloys
Original language description
Aluminium based alloys are well known for their low density and convenient mechanical properties filling the imaginary gap between titanium alloys and common aluminium alloys. Aluminium alloys prepared via centrifugal atomization technique (CA) can contain higher amount of transition metals (Fe, Cr, Mn), characterized by low diffusivity in solid aluminium, enhancing their properties, especially thermal stability. In this work, AlSi23Fe8Cr1 and AlSi23Fe8Mn5 (in wt. %) alloys were prepared via centrifugalatomization. Prepared powders were compactized by uni-axial pressing at 6 GPa and 450 °C for 60 min. The microstructure of prepared powders and compact samples was studied by light (LM) and electron scanning microscopy (SEM). Phase composition was determined by X-ray diffraction (XRD). The thermal stability of the alloys was studied by mechanical testing after long-term annealing at 300-400 °C and by creep testing at 300 °C and compressive stress of 250 MPa. Obtained results were compar
