- Аннотация: The mechanochemically synthesized Cu–20 wt % Al alloys are studied by the X-ray diffractionanalysis and scanning electron microscopy. It is shown that, after 20 min of mechanical activation, the singlephaseintermetallic compound Cu9Al4 with crystallites ~3 nm in size, low microstrains (~0.03%), and particlesize in the range from 0.2–0.4 to 2–4 μm is formed. The morphological characteristics of the solid solutionof aluminum in copper, which has been mechanochemically synthesized from the Cu–10 wt % Al alloy, arestudied. It is demonstrated that the solid solution is composed of platelike particles 10–50 μm in planar sizeand 2–10 μm in thickness. The scanning electron and optical microscopy data show that the Cu(Al) solidsolution produced by the spark plasma sintering at 700°С are characterized by the low residual porosity(<0.5%). The Vickers hardness is 290 ± 30 HV.
