Macroanalysis by the fractures’ type (Part 1)
Fracture is the failure surface of a product or the whole piece of metall. According to cracks fracture cracks, holes, blowholes, stratifications, gaps, large s...
Growth of crystals (part 1).
Growth of nucleuses happens as a result of migration of liquid atoms to them. However, in a lot of cases, it doesn’t come to this one-faced atoms transfer. Atom...
Generation of crystals in liquid (Part 4).
To a large extent, the process of generation is affected by the inclusion surface’ topography. If there are depressions on the surface, the critical dimen...
