- Abstract
- The thermal stability of thin wires made of six aluminum alloys Al–0.25%Zr, additionally alloyed with Si, Er, Hf or Nb, has been studied. Aluminum alloy workpieces were obtained by induction casting, followed by stabilizing annealing (450°C, 1 h) and severe plastic deformation to fragmentation the cast structure. The wire with a diameter of 0.3 mm was made by drawing at room temperature. The thermal stability of the mechanical properties, microhardness, and specific electrical resistivity (SER) of stabilized aluminum wires has been studied. As the annealing temperature increases, a monotonous decrease in the tensile strength, microhardness, and SER of the wires occurs. It is established that the ductility of the wires depends nonmonotonously (with a maximum) on the annealing temperature. The results of studies of the thermal stability of the properties of stabilized wires are compared with the characteristics of wires that have not been subjected to preliminary stabilizing annealing (450°C, 1 h).
