Conclusions

  1. 1.

    All the phosphides investigated except gallium and indium phosphides have a considerable modifying effect on the structure and properties of hypereutectic Silumins.

     
  2. 2.

    Aluminum phosphide has the largest effect on these alloys.

     
  3. 3.

    Modification with AIIIBV phosphides increases the microhardness of the primary silicon grains.

     
  4. 4.

    If the operating characteristics of parts do not change with the addition of copper and zinc to hypereutectic Silumins at levels exceeding GOST or TU specifications then it can be recommended that these alloys be modified with copper phosphide (the most suitable technologically) or zinc phosphide (the cheapest).
