Аннотация: Abstract—A hypereutectic Al–8Ca–2Mn–1Ni–0.3Fe–0.3Zr (composition is given in weight percent) alloy prepared by casting in an electromagnetic crystallizer is subjected to hot rotary swaging (RS) from an initial diameter of 14.5 mm to a final diameter of 5.2 mm. RS is found to lead to the formation of an ultrafine grain–subgrain microstructure. The alloy subjected to RS exhibits a yield strength, ultimate strength and relative elongation of 269 MPa, 342 MPa, and 4.5%, respectively; in this case, fracture is completely ductile and the linear thermal expansion coefficient is low, at the level of traditional hypereutectic silumins.
