The surface work of the critical dimension nucleus formation.
In the formation of the crystallization nucleus, the part of the energy is released when the bulk phase occurs, and part of the work is spent on creating the su...

The isolation of the excess phase from the supersaturated solid solution (Part 2).
With the appearance of β-phase crystals, the α-solution surrounding them is depleted by component B. Near the β phase, the solid α-solution has the Сг compositi...
The crystals shape (Part 2).
With the increase in the growth rate of crystals, the dimensions of the cells decrease. With intensive heat removal through the solidified metal, when the growt...
The metal structure basis (Part 4).
The metal melting in a small area, leads to the appearance of shrinkage stress. Even if the external fixation of the sample was ensured during the heating and c...
The crystallization process mechanisms.
The crystallization takes place in two stages: in the beginning, nucleation center arise, and then nucleation center grow. There are two mechanisms for the nucl...
