“…Due to the chemical composition of Ti6Al4V they are characterized by high creep resistance, brittleness resistance and thermal stability. The most important alloying addition of Ti6Al4V is aluminium whose job is to reduce density of these alloys [2,3].…”

Titanium based alloy -Ti6Al4V and nickel based alloy -Inconel 718 belong to the group of difficult-to-cut materials. Thanks to their unique properties they can be used in constructions that need to withstand the high reliability requirements which are required inter alia in the aircraft industry. The physical properties of cutting layer, including residual stresses, play an important role during exploitation of products made out of difficult-to-cut materials. In the article, the method of residual stresses determination is described and the exemplary results of carried out studies are provided. Described method is based on the measurement of the defects in the crystal lattice. The carried out studies show that the state of residual stresses, in a subsurface layer, can be formed by the selection of machining conditions.

Ti6Al4V alloy has been found to be the leading material for hip replacement due to its biocompatibility and good yield strength; however poor corrosion and wear properties are experienced in human tissue surroundings. Laser metal deposition was accomplished on Ti6Al4V alloy using: 25Hafnium, 50Niobium, and 25Zirconium reinforcements with the aid of Nd:YAG Rofin Sinar laser. Characterization of the produced deposits was carried out by optical microscopy, scanning electron microscopy/energy-dispersive X-ray spectroscopy and X-ray diffraction. Hardness, corrosion and wear analyses were also done. Microstructure of 25Hf-50Nb-25Zr coatings indicated homogeneous microstructures of both α and β phases. More α acicular phases were formed than β phases. The 25Hf-50Nb-25Zr coating on Ti6Al4V reduced the content of aluminium and vanadium on the substrate. Maximum hardness value and lowest volume wear rate were obtained at laser power of 1250 W with hardness values of 599.18 HV and 0.6 m3 volume wear loss. Improvement in corrosion resistance of 99.98% was obtained. It was established that improved properties were obtained after laser surface cladding of 25Hf-50Nb-25Zr on Ti6Al4V alloy.

“…In [11] comparison of surface roughness during CO2 laser cutting of tungsten alloy plate using oxygen as assist gas, based on control charts made by statistical process control (SPC) approach is reported. For further analysis, it is especially interesting to analyse uncommon materials and alloys where the common knowledge is not applicable [12].…”

Laser cutting is a popular manufacturing process utilized to cut various types of materials. There are many non-linear interaction factors responsible for the performance of the laser cutting process. Identification of dominant factors that significantly affect cut quality is important. In this paper, the effect of the process parameters is analysed on the laser cut quality of an uncommon alloy, the tungsten alloy sheet with thickness of 1 mm. The experiments are conducted at three levels of the selected process parameters such as assist gas type (oxygen, air and nitrogen) and assist gas pressure. Taguchi design of experiments is used to obtain the optimum conditions through the study of signal to noise ratio for three quality characteristics such as kerf width, heat affected zone and surface roughness. Results of this study indicate that the optimal assist gas pressure is entirely different for kerf width, heat affected zone and surface roughness. The nitrogen as assist gas is suggested as the optimal assist gas for all of three quality characteristics.
