Mechanical parameters of copper-aluminum cermets as functions of temperature

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    Cu-Al alloys made by powder methods show higher resistance to compression than do cast ones of the same composition in the range 20–300°C.

  2. 2.

    This increased resistance in Cu-Al cermets is associated with the oxides, very small grain size, and pronounced inhomogeneity.

  3. 3.

    Homogenization of the cermets produces mechanical properties at high temperatures better than those found for unhomogenized materials.

  4. 4.

    The strengthening of Cu-Al cermets on annealing after cold deformation is rather different from that for cast alloys; in particular, it persists over a wider temperature range and occurs for low aluminum contents.
