In a world of rapidly changing technologies, additive manufacturing stands out as an innovative approach to creating objects using 3D computer models. Since its introduction in the early 1980s, this technology has undergone significant changes and is now widely used in various industries, from aerospace production to medicine.
Combining and reducing costs
One of the key advantages of using additive technologies in the manufacture of metal products is the ability to combine several parts into one. This is achieved due to the ability to create complex components in a single unit, which leads to a reduction in the number of elements in the finished unit. This approach significantly reduces production costs, since products are created directly without the use of complex equipment.
Design freedom and integration
Additive technologies also make it possible to produce parts of complex shape, including the creation of internal channels, small nets or thin-walled elements. This flexibility in design opens up new horizons for creating innovative products. In addition, additive technologies are easily integrated into existing technological processes, which helps to improve them and reduce the total number of operations.
Additive manufacturing in metalworking provides unique opportunities for the efficient and innovative creation of metal products. Modern technologies not only improve traditional production methods, but also open up new opportunities in product design and functionality.
There are two main types of additive technologies that differ in the use of consumables:
However, in order to fully unlock the potential of additive manufacturing, it is necessary to carefully study the processes of structure formation in materials. Research conducted using transmission electron microscopy is key to this understanding.
Metal hardening during additive manufacturing has a direct effect on the microstructure, defects and mechanical properties of final products. IN this study scientists focused on the analysis of thermomechanical deformation regimes, in particular, on the effect of thermomechanical stress on the formation of a dendritic structure during laser melting of the Inconel 625 alloy.
Using transmission electron microscopy, it was possible to study in detail the processes of dendritic structure formation. The knowledge gained was very valuable for optimizing strategies for printing metal elements in order to obtain the desired microstructural features. Thanks to understanding these processes, it has become possible to determine the orientation of dislocations and the nature of grain boundaries.
Effective control of thermomechanical deformation regimes has made it possible to create specific microstructural elements. This, in turn, made it possible not only to improve the quality of manufactured parts, but also to create innovative products with predetermined mechanical properties. For example, the use of a laser beam using pulses helped reduce the grain size of the crystal, which led to an increase in the strength of the part.
though PZPS does not specialize in the production of parts using additive technologies, we can offer production various nickel-chromium alloy belts. These materials are highly durable and corrosion resistance, which makes them popular in various industries.
