The crystal growth (Part 3).
At the large overcooling, the mechanism of the crystals growth by means of dislocations and steps is replaced normal, is not connected with the origin of new at...
The polymorphic transformations in metals (Part 2).
The second feature of the phase transformations in solid metals is connected with smaller, than in liquid, atoms mobility. The diffusion velocity in liquid meta...
The cast metal macrostructure.
The dendrite structure and the crystallization zones of cast metal can be detected by the deep etching of macrosection in 15% water solution of ammonium persulp...
Macroanalysis by the fractures’ type (Part 2).
