to incoherent, which reduces the energy barrier to nucleation of M-phase at the
dispersoid (Kikuchi et al., 1993). Lower temperature of dispersoid formation (
lower temperature of ingot homogenization) can increase solute loss during
quench.

Lightweight Alloys for Aerospace Applications
Coarsening A dispersoid s ability to counteract boundary pressure is inversely
dependent on its size. At some dispersoid size the particle will become ineffective
and recrystallization will occur. Knowing the size limit at which a particular ...

When the dislocation now rides up over the dispersoid particle on its arrival side
as shown schematically in fig. 5, bulk dislocation of higher line energy is
exchanged for a segment of lower energy, on the one hand, while, on the other,
the total ...

Rapidly Solidified Alloys: ...
Both Er2O3 [83-87] and Y2O3 [83,88] were found to produce a fine dispersoid in
rapidly solidified titanium alloys. Virtually no dis- persoid was present in the RS
condition [87-89] provided solid-state cooling was- sufficiently fast. Aging at ...

The dispersoid particles are Cu-rich and Mn-rich , most probably CuAl2 and
Al2rjCu2Mn3 Figure (3) also shows a high density of helical dislocations which
form during quenching from the solution heat-treatment temperature. Figure (4)
shows ...
