Ultra Low Carbon Steel

This paper investigates the surface texture evolution after a short phase transformation annealing in low vacuum on ultra low carbon steel sheets alloyed with high Mn and Al and the cold rolled steel sheets of industrial composition alloyed with silicon. The ultra low carbon steel sheets with high Mn and Al show surface monolayer which has a characteristic surface texture components <100>//ND texture and microstructure with special grain morphology. Contrastingly, the industrial composition alloyed with silicon does not show specific surface texture components inspired by surface energy anisotropy at the surface. The composition depth profiling investigations performed on the all steel sheet surface shows that oxidation characteristics of alloying elements at the metal vapour interface have played a decisive influence on surface texture evolution. Further, transformation annealing in higher vacuum reveals that surface texture can be obtained in an industrial composition alloyed with silicon.

Effect Of Oxygen

An experimental study of the effect of the content of the oxygen in the auxiliary process gas on the laser cutting speed and the quality of the cut-off zone surface was made. For the research, the auxiliary technological gases of the brand LAZAL, produced by Air Liquide (99.95% oxygen content) and Energo grade (99.7% oxygen content), were used. For the experiments, a low-carbon steel with a thickness of 8 mm and 3 mm was used. The main objective of the study was to increase the productivity of laser equipment by increasing the cutting speed. It is established that the use of oxygen in laser cutting as an auxiliary gas makes it possible to increase the cutting speed, to decrease the power of the laser installation, or to increase the thickness of the cut metal at the same power.
