The polymorphic transformations in alloys (Part 1).
The impurities are important in the polymorphous transformations. The nature of the influence of impurities is related to their solubility in the metal. If the ...
The non-existence of defects monitoring in the weld seams (Part 1).
This test group is designed to assess the quality of the metal structure and the non-existence of defects in it. The non-existence of defects monitoring is usua...
The dependence of atoms ionization energy on the plasma temperature (Part 2).
The value of Wи for each atom cannot be precisely calculated. However, if we assume that the quantity Wи and depends linearly on T, then its value can be calcul...
Remains of the welding wire in the weld seam.
The wire remains in the seam in violation of the synchronization and the wire feed speed of welding head. The defect is not valid and the junction with the spec...
