Abstract

Copyright (c) 1996 Elsevier Science B.V. All rights reserved. In the concentration range 75-100at.%Co, the isothermal section at 1150°C of the system Sm-Co-Zr is determined experimentally. The following features are evidenced: a very small Sm solubility in Co, Zr₂Co₁₁, and Zr₆Co₂₃, an extended Zr for Sm substitution rate in SmCo₃, Sm₂Co₇ and Sm₅Co₁₉, and a significant Zr solubility in SmCo₅ and Sm₂Co₁₇ that induces the existence of a continuous ternary single phase 1:7. On the basis of the lattice parameter data, the formation of this phase by the substitution of Co dumbbells and/or Sm atoms for Zr atoms is proposed.
