“…1). Technologies for the production of such structural elements of the oil cooler are different, as well as the range of applicability of the obtained tubes and their thermal physical properties [Turtelli 2006, Murcinkova 2013. Ribbing is necessary to increase the effective heat exchange area, through which the heat will be removed into the environment.…”

“…Effect of molybdenum, as noted authors [3,6,16], the most effective in co-introduced with metal carbide elements [18]. In addition, from the literature [3,5,7,12,15,16], the authors of many studies do not have a clear answer regarding the effect of molybdenum on the microstructure [19], composition and condition of non-metallic inclusions [20,21,22], which mainly determine the corrosion-mechanical and technological properties of welding joint [23]. In addition, it should be noted that in the literature there are no data on the use of molybdenum as alloying modifier in the main type of electrode coatings for welding low carbon steels used in the construction of pipeline construction as heat-power transport communications sector, industrial production, and urban heat networks [24,25,26].…”

Still existing scientific, technical and technological developments to improve the quality of welded joints of metal pipe structures contain contradictions and uncertainty about the effects of alloying elements, such as molybdenum, mechanical and visco-plastic properties, as well as metallographic component joints. All this indicates the need for a systematic study of these problems for the development of rational metallurgical and technological measures to significantly improve the technological and corrosion-mechanical properties of weld metal. Metallographic studies, using laboratory equipment with high identifying ability, found that the doping of weld metal with molybdenum in the amount of 0.2-0.4% causes fragmentation of ferrite-pearlite structure, including carbides Mn and Fe, and also reduces the number and size of non-metallic inclusions – sulfides, oxides and silicates. Moreover, non-metallic inclusions have a dispersed appearance, which promotes plasticization of the structure, which directly increases the viscous-plastic characteristics and resistance of the metal joints to crack formation. Based on the results of metallographic research, the optimum content in the weld metal of the alloyed element – molybdenum, which is 0.2-0.4%, is determined.

“…According to the aforementioned facts the amount of air entrapment in the cast volume can be influenced by selection of technological parameters [Turtelli 2006, Kanazawa 2016, Trytek 2016, Meethum 2017]. The publication [Majernik 2019c] proved correlation of technological parameters (such as melt temperature prior to entering the mould shaping cavity), velocity of meld flow in the ingate and filling period of mould shaping cavity with the cross section of the main and lateral runner.…”

Technology of metal die casting is characterized by production of casts complicated as to shape yet with positive mechanical properties and with high repeatability of production. However, casts are porous to a certain extent which eventually reduces their mechanical properties. One of the significant methods of porosity reduction of casts rests in correct design of a gating system. The submitted paper studies the influence of cross-section area of a runner on air entrapped in the cast volume. Seven alternatives of runners with the identical structural organization and variable cross-section area were compared. In case of a gating system design there was an assumption made that the runner with the largest cross section would deliver the lowest possible velocity to the melt before reaching the runner which would result in the lowest possible values of air entrapment. The air entrapment in the cast volume is evaluated behind the cores which were evaluated as critical points with regards to further processing. The results reached during examination of the melt flowing through runners proved the aforementioned assumption, yet the values of air entrapment in die casts volume did not show remarkable differences. In its final part, the paper clarifies the reached results and recommendations which should be taken into consideration when designing the gating system structure.
