Precipitates in a material are generally impurity phases that segregate during the solidification process. Precipitation can produce many different sizes of particles and can have vastly different impacts on material properties. Intergranular precipitates segregate into grain boundaries and take up volume between grains whereas intragranular precipitates are contained within grains and disrupt the crystal structure.
