A method of manufacture and some properties of sintered 20Cr-80Ni Nichrome

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

Summary

  1. 1.

    20Cr-80Ni Nichrome powder obtained by the method of simultaneous reduction of oxides has excellent technological characteristics, and specimens compacted from this powder can easily be sintered in a hydrogen atmosphere. The optimum sintering parameters are a temperature of 1250°C and a holding period of 1–3 h.

  2. 2.

    At a porosity not exceeding 15–20%, sintered 20Cr-80Ni Nichrome specimens have relatively high mechanical properties and excellent oxidation resistance at up to 1100°C.

  3. 3.

    The Nichrome powder investigated may be recommended for use as a metal base of some sintered materials, including sealing materials intended for service in high-temperature gas turbine units.
