Kurzfassung englisch:
A identify conditions of laser heating for warm forming of materials with a ferritic-martensitic structure was performed. The laser
source was a fiber laser with maximum output power of 1500 W. The beam was transformed to an elliptical ring with use a
plano-convex lens and axicon. Study of the microstructure allowed revealing fibrous structure of metal, formed during the manufacture of blanks by rolling. Place of plastic deformation is characterized by a local decrease the thickness profile. To eliminate of this defect, is advisable to use the diffractive optical elements, which redistribute the power density of a laser beam.

Schlagworte:
