Effect of zirconium, cerium, and nitrogen on the properties of a cast chromium-base dispersion-strengthened alloy

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

Conclusions

An analysis of the chemical inertness and wettability of various nonmetallic compounds has shown zirconium nitride to be the most suitable strengthening phase for a chromium-base alloy. Endogeneously strengthened alloys have been produced having values of high-temperature strengthσ 900t of between 270 and 340 MPa and of room-temperature ductilityδ 20 of between 5 and 44%. The properties of such an alloy are determined by the size and uniformity of distribution of its strengthening particles, while these in turn depend on the zirconium-tonitrogen ratio in the alloy.
