Abstract：

Topologically　close-packed　(TCP)　phases　in　Ni-based　single　crystal　superalloys　are　known　to　exhibit　different　morphologies　and　orientation　relationships　within　the　matrix.　This　study　investigated　the　influence　of　chemical　composition　on　lattice　parameters,　which　in　turn　determine　the　interface　lattice　misfit　between　TCP　phase　and　matrix　and　thus　shape　and　orientation　of　the　TCP　phase.　In　this　study,　TCP　phase　particles　of　different　morphologies　were　formed　by　ageing　at　different　temperatures.　The　level　of　TCP-phase　element　enrichment　was　found　to　increase　with　increasing　growth　time　and　ageing　temperature,　and　thus　leads　to　a　same　evolution　behavior　of　the　atomic　volume.　(C)　2018　Acta　Materialia　Inc.　Published　by　Elsevier　Ltd.　All　rights　reserved.
