Mechanochemical Synthesis of Cu–Al Alloyed Powders and Their Consolidation by Spark Plasma Sintering

The mechanochemically synthesized Cu–20 wt % Al alloys are studied by the X-ray diffraction analysis and scanning electron microscopy. It is shown that, after 20 min of mechanical activation, the single-phase intermetallic compound Cu9Al4 with crystallites ~3 nm in size, low microstrains (~0.03%), a... View More
