In today’s dynamically evolving competitive environment, characterized by uncontrollable globalization, the beginning of digitization of phenomena and processes or the shared economy result in the deepening of the fourth industrial revolution. In this competitive environment, it is necessary to focus on regions where the socio-economic development of the area is less effective. The aim of this paper is to analyse cross-border entrepreneurship in the Euroregion Beskydy from the viewpoint of Czech and Polish business entities. This paper integrates the study of influences on cross border entrepreneurship, authors use the questionnaire survey and structured interviews as well the influences are systematically compared and to move this we use multi-criteria decision analysis. Results indicate that the important areas in the Euroregion Beskydy that need to be focused on, in order to remove the barriers to cross-border entrepreneurship, has been defined as sustainable and responsive to the current business environment.

W dzisiejszym dynamicznie rozwijającym się środowisku konkurencyjnym, charakteryzującym się niekontrolowaną globalizacją, początek cyfryzacji zjawisk i procesów lub wspólna gospodarka powodują pogłębienie czwartej rewolucji przemysłowej. W tym konkurencyjnym środowisku konieczne jest skupienie się na regionach, w których rozwój społeczno-gospodarczy obszaru jest mniej skuteczny. Celem niniejszej pracy jest analiza przedsiębiorczości transgranicznej w Euroregionie Beskidy z punktu widzenia czeskich i polskich podmiotów gospodarczych. Dokument ten integruje badanie wpływów na przedsiębiorczość transgraniczną, autorzy wykorzystują ankietę i ustrukturyzowane wywiady, a wpływy są systematycznie porównywane, a aby to zmienić, korzystano z wielokryterialnej analizy decyzji. Wyniki wskazują, że ważne obszary w Euroregionie Beskidy, na których należy się skupić, w celu usunięcia barier dla przedsiębiorczości transgranicznej, zostały zdefiniowane jako zrównoważone i dostosowane do obecnego otoczenia biznesowego.

Observations were made in orientated state of inter-metallic Ni3Al based compound alloyed by zirconium. Zirconium in the form of wire or plasma melted foundry alloy Ni-Zr were used for preparation of the samples. The samples were cast by induction vacuum casting into the shape of cylinders. These castings were then directionally solidified in corundum tubes with the specified apex angle in a two-zone crystallisation furnace. Used rate of directional solidification was 50 mm/h. Cross sections and longitudinal sections of individual samples were used for determination of porosity, micro-hardness and for evaluation of character of created structures. It was established that the basic matrix contained formations of Ni3Al and elongated formations of Ni5Al3. Inter-dendritic regions contain eutectics with lamellar structure, which is formed by the Ni3Al phase and by the Zr-rich phase. Microhardness in the samples was determined in detail on the surface of the scratch pattern in polished state in accordance with precisely defined procedure, both in longitudinal and cross section. The scratch patterns were afterwards slightly etched in order to determine microhardness in individual phases and on grain boundaries. Microhardness was measured on microhardness tester FM-100 with use of the measuring unit "automatic microhardness testing system FM-ARS". It is very interesting that no big differences were found between the values of microhardness in the basic phase of Ni3Al rich in zirconium and grain boundaries, where this value varied approx. within the interval from 360š40 HV 0.05. Only eutectics formed by the Ni3Al phase and by the Zr-rich phase showed an increased microhardness. Evaluation of structure has been further completed with determination of porosity. Porosity in these samples was not too high and its value is of the order of hundreths of percent.

For purpose of investigation of high purity materials Ni-22Al-1B and Ni-24Al-1B alloys (all in at.%) were prepared by melting of basic components in vacuum induction furnace. The cylinder castings were afterwards directionally solidified in two-phase super-kanthal resistance furnace working on Bridgman's method principle. Re-melting proceeded in corundum tubes with the apex angle at 1 550°C and at uniform rate 50 mm/h. The alloys fabricated by this way were crossly and longitudinally cut and the sections were used for determination of porosity, micro-hardness and for evaluation of micro-structure. The common feature of micro-structure of the both alloys was its coarseness. Further features of structure were different. Long parallel lines of mesh passed through the sections with 22 at.% Al. It was not observed in the sections with 24 at.% Al. B-rich phase was inside of these structures. Definite composition of phase is still determinating for reason of boron low sensitivity of many detection devices. Micro-hardness determination of the samples of both alloys was measured on micro-hardness tester FM-100 with automatic testing unit FM-ARS 900. Two types of measurement were carried out. The first on unetched samples. This value characterized sample as component. The second it was measured micro-hardness of structures presented on scratch patterns after their etching. Average values of matrix micro-hardness were about 270š20 HV 0.05. The B-rich phase had much greater values. It is assumed, that phase can cohesively strengthen these alloys. The last measurement carried out on the samples of both alloys was determination of their porosity. Resultant values were approximally 0.05š0.03%.
