Opis:: The investigation was performed on nickel-base superalloys, with nickel being the most influential alloying ingredient. After thermo-mechanical preparation and corresponding processing, femtosecond laser beam machining has been performed. The laser wavelength was 800 nm. The exposition time, during which the samples have been exposed to the pulses of femtosecond laser beam varied, as well as the average output power. The changes of both the output power and the exposition time enabled the samples to be irradiated with different total energy during each exposition. The changes in samples microstructure were observed with optical and scanning electron microscopy, with energy-dispersive spectrometry, and analyzed as well. Microhardness measurements of both base material and ablated spots have been performed.

Opis:: The investigations were carried out on chrome nickel steel and nickel based superalloy samples thermo-mechanically treated to obtain optimal mechanical properties and surface stability. Chrome nickel steel and a few nickel based superalloys samples were exposed to the laser beam before creep deformation process. The second group of nickel based superalloy samples were exposed after the creep deformation. The damages occurred by exposing of chrome nickel steel and nickel base superalloy samples to the ruby laser were analyzed by scanning electron microscope and energy-dispersive X-ray spectrometry. In this paper, the influence of laser dynamical regime (MW/$mm^{2}$) to the microstructural changes of heat treated chrome nickel steel and nickel based superalloy are analyzed and discussed.

Opis:: Due to the specific conditions of manufacturing, processing and utilization of nickel-base superalloys, the implementation of contemporary precision techniques is necessary in the research of the alloys features. Multi-component nickel-base superalloys, with about of 50% of nickel content, are commonly exploited in the conditions of high temperatures and pressures as well as in various aggressive operating environments. For successful quality control, which includes the monitoring of the changes in the alloy microstructure, fine-scale structure investigations are necessary. In this work, the samples of nickel-base superalloys have been exposed to 800 nm femtosecond laser in various operating regimes. Surface damages and dents caused by femtosecond laser pulses have been observed by optical and scanning microscopy.

Opis:: The experimental treatment of chosen material with laser beams, starting from continuous wave up to fs pulses, produces the necessity to find the common and sophisticated theoretical approaches to interaction modeling. For chosen materials, some laser treatment and damage analyses are performed. The provoked stresses and parameters of transport processes (penetration depth) are calculated by using the programs for electrical circuit analyses. Some inconsistencies in the treatment of large area laser-material interaction are discussed.
