Abstract:
Heterogeneous welded joints – type ferrite/austenite is inseparable part of structure for energy industry. Welding conditions and post weld heat treatment have a significant impact on the structural stability of welded joint. The structure determines resulting mechanical properties that determine lifetime of these joints. At the same time in microstructure changes in heat affected zone of the base material is diffusion of carbon through the weld interface. This work is focused on the analysis of structural stability of heterogeneous weld carbon/austenitic steel, which was formed carbon steel 2

The Poincare equations, also known as Lagrange's equations in quasi coordinates, are revisited with special attention focused on a diagonal form. The diagonal form stems from a special choice of quasi velocities that were first introduced by Georg Hamel nearly a century ago. The form has been largely ignored because the quasi velocities create so-called Hamel coefficients that appear in the governing equations and are based on the partial derivative of the mass matrix factorization. Consequently, closed-form expressions for the Hamel coefficients can be difficult to obtain and relying on finit

The project presents a solution of geometrical influence on the thinning of the stamped part with thickness 0.3 mm. It can be made from stainless steel X2CrCuTi18, X5CrNi18-10 or X5CrNi18-10 with additional heat treatment. Based on the literature review the technology of drawing was described and a theoretical analysis of shallow drawing was carried out. Material models for numerical simulation and parametric model of punch and die were created. The analysis of thinning dependence on the geometry of the dimple was performed using FEM analysis in ANSYS software. The smallest thinning of value 9

Despite their small size, phytoplankton represents up to 50% of the global primary production of the Earth and serves as a connector between oceanic and atmospheric processes. Therefore, phytoplankton constitutes a central pillar in the comprehension of the cycles of mass and energy in the oceans. Their different attributes like size, abundance, community composition, functions, pigment complex and taxonomy provide relevant information to understand the processes of global change.

La Argentina es un país conocido en el mundo a partir del siglo XIX por su producción agrícola y ganadera. A pesar de ello, su ubicación geogràfica en un área de acentuada fertilidad pesquera y su extenso litoral marítimo se conjugaron con otros factores (políticos, económicos, sociológicos, etc.) para que, casi en secreto, se desarrollara un país pesquero. Si bien la población de Argentina no consume pescado más allá de los 5 Kg. por persona al año, y este consumo está muy sesgado socialmente, la concentración de población en la ciudad de Buenos Aires fue un mercado suficiente como para que a
