granica ziarna

This means that the grain boundary will migrate towards the the curvature.

When it reaches a grain boundary, the dislocation will disappear.

The areas where these crystallite grains meet are known as grain boundaries.

Two main mechanisms for altering grain boundaries have been defined.

The same effect can cause precipitate particles to form at the grain boundaries of a solid.

This reduces the total area of grain boundary and hence the stored energy in the material.

In common materials, crystallites are large enough that grain boundaries account for a small fraction of the material.

Thus, when the steel is later heated up and worked, the melting at the grain boundaries does not occur.

This helps dislocation movement along grains and across grain boundaries.

In the early 1950s two groundbreaking series of papers were written independently on the relationship between grain boundaries and strength.
