Abstract

  Compositions with tie-lines between the γ and δ phases in a binary Re-Ni system were investigated at 1423, 1573, and 1773 K by heat-treating of Ar-arc-melted Re-40 at%Ni alloy. The microstructures of the Re-40 at%Ni alloy which had been water-quenched after various heating times were observed and their concentration profiles for Re and Ni were measured using an electron probe micro-analyzer (EPMA). The Re-40 at%Ni alloy consisted of the γ and δ phases.<br>    The tie-lined compositions of the γ and δ phases are summarized as follows (in at%); γ: 13.4Re-86.6Ni, δ: 71.7Re-28.3Ni at 1423 K, γ: 16.4Re-83.6Ni, δ: 69.3Re-30.7Ni at 1573 K, γ: 20.2Re-79.8Ni, δ: 65.3Re-34.7Ni at 1773 K.<br>    The Re-Ni alloy powder sintered using the Spark Plasma Sintering (SPS) method were investigated. Solubility limit of Ni in the δ phase in the binary alloy system at 1423 K was found to be 28.3 at%Ni.<br>
