The strength and plasticity of a series of rapidly solidified high-temperature aluminum alloys determined in tensile tests are analyzed over a wide temperature range. The properties of the following systems are studied: Al–Fe–Ce, Al–Fe–Cr–(TM), Al–Cr–Zr(Mn), and Al–Fe–V(Mo)–Si. The effect of the doping content and rapid solidification technique on strength is examined. The best samples of green products show 550–600 MPa strength at room temperature and at least 200–250 MPa at 300°C. The strength of Al–Fe–Cr–(TM) alloys with a high volume content of quasicrystals is approximately 100 MPa higher at 20 and 300°C, while their elongation is 50 to 67% lower than the corresponding characteristics of other materials.
