Evaluation of Metal Powder for Additive Manufacturing of Maraging Steel

Popis výsledku v původním jazyce

Additive technology is very usable method for produce of quick prototypes or small series. 3D print can be used to obtain the products with complex geometries from powder materials, which have after printing comparable properties with a standard material. There are several metallographic issues connected with 3D printed microstructures. Laser beam processing is usually accompanied with high heating and cooling rates and therefore also with high thermal gradients. This is the reason why non-equilibrium phases and structural components, which are very different from common materials, can occur in the final microstructure. The metal powder is on the start of the sintering process. Its quality is very important for the results of mechanical properties of final components. This paper deal with quality of metal powder for additive manufacturing of maraging steel 1.2709 (X3NiCoMoTi 18-9-5) by method laser sintering. The size of particles, shape and chemical composition was compared in different possibilities of using for 3D print. The microstructure of powder particles was focused too. Comparison with microstructure of final component is interesting.
