Physical and chemical processes of alloys formation during mechanical alloying. 1. The stage of granules reaction sintering

Physical and chemical processes of alloys formation under mechanical doping were studied using scanning and transmission electron microscopy methods. Under the treatment in triborator definite particles refining, their saturation with defects and partitial formation of defect substructure with high stress fields was found to be achieved. Due to these processes solid phase alloying take place with new Cu₉Al₄, α-Al₂O₃ and γ-Al₂O₃ phases formation on the internal interfaces. Residual oxygen is trapped on defects.
