Test Methods and Properties of Materials


  1. 1.

    An experimental study was carried out of the effect of temperature and porosity on the impact strength of sintered materials (bronze, bronze-graphite with 3% graphite, bronze with 5% boron nitride, and iron-nickel and copper-nickel alloys) at low temperatures.

  2. 2.

    It was established that the variation of impact strength as a function of temperature has a similar character for cast and sintered materials.

  3. 3.

    It was shown that, with increasing porosity, the maximum on the impact strength vs temperature curve becomes flatter.

  4. 4.

    It was established that the upper limit of the brittleness range for the iron-nickel, bronze, and bronze- 3% graphite materials lies at about 230° K and that of the copper-nickel material at about 123° K. The bronze- 5% boron nitride material is brittle in the whole temperature range investigated.
