    • Abstract
  • After a completely heat treatment, DD11 nickel-based single crystal superalloy was treated by stressed aging at 1 070℃ under 100 MPa and unstressed aging at 1 070℃, respectively. The precipitation behaviour of topologically close-packed (TCP) phase after aging under different conditions was analyzed. The results show that no TCP phase precipitated in the tested alloy after stressed aging and unstressed aging for 50 h. After aging for 100 h, TCP phase began to precipitate in dendrite region; the precipitation amount of TCP phase increased with the extension of aging time. For the same aging time, the precipitation amount of TCP phase after stressed aging was less than that after unstressed aging. The stress did not change chemical composition and crystal structure of TCP phase; the precipitated TCP phase was μ phase.
