Abstract
It is proposed that the peritectic reaction, involving dissolution of
211 particles into the liquid and precipitation of solid 123, cannot o
ccur at the peritectic temperature for thermodynamic reasons and cryst
allization of the peritectic phase occurs directly from the liquid. Th
e aligned grain structure is explained through sympathetic nucleation
of new 123 grains on existing grains.
