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...

Earlier we considered those types of tests that allow us to know the mechanical properties of metals. The metals also have important chemical properties. In fac...
The studies have shown that the extent of the cathode and anode zones of the arc is very small: : lк = 1·10-5 см; lа = 1·(10-3…10-4) cm. Then the length of t...
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 takes place in two stages: in the beginning, nucleation center arise, and then nucleation center grow. There are two mechanisms for the nucl...
