Strengthening of a fully lamellar TiAl + W alloy by dynamic precipitation of β phase during long-term creep

In a fully lamellar Ti–48Al + W alloy, β phase precipitated by aging lowers the primary creep rate significantly. However, dynamic precipitation of the β phase during long-term creep reduces the steady-state creep rate of the unaged alloy close to that of the alloy in the aged condition.
