<abstract xmlns="http://www.w3.org/1999/xhtml">The use of secondary aluminum alloys is increasing because it contributes to the decrease of production costs. However, these alloys contain bigger amount of iron. Iron has a negative effect and therefore its elimination is necessary in order to add some elements, which are also called correctors of iron. The most frequently used corrector is manganese. Another quite often used correctors are chromium, potassium, magnesium, vanadium. In the following work, vanadium is used as a corrector of iron phases. The application of vanadium in aluminum alloys has a positive impact on their mechanical properties, increases the tensile strength, ductility and hardness. As experimental material AlSi6Cu4 alloy was used. It was alloyed by master alloy AlFe10. After adding to the master alloy the iron content, the critical value in the alloy exceeded. Vanadium was added to AlSi6Cu4 alloy in different quantities. The image analysis (software NIS-Elements) was used for quantifying the amount of iron based intermetallic phases and determination of average values.</abstract>

Internal damping reflects the ability of the material irreversibly dissipating mechanical energy oscillations. It means that the material of high internal damping ability is able to significantly reduce the vibration amplitude. Internal damping is, generally, dependent on many factors (temperature, material purity, grain size, mechanical and thermal processing, etc.) and its value is determined by interactions between various mechanisms dissipation of mechanical energy. Ultrasonic resonance method was used in experimental measurements, which is based on continuous excitation of oscillations of the specimen, and the entire apparatus vibrates at a frequency which is near to the resonance. Starting resonance frequency for all measurements was about f = 20470 Hz.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Nickel base superalloys are hi-tech materials intended for high temperature applications. This property owns a complex microstructure formed by matrix of Ni and variety of precipitates. The type, form and the amount of these phases significantly affect the resulting properties of these alloys. At sufficiently long exposure to high temperatures, the transformation phase can occur, which can lead to degradation of properties of these alloys. A cyclic plastic deformation can accelerate these changes, and they could occur at significantly lower temperatures or in shorter time of exposure. The aim of this study is to describe phase transformation, which can occur by a cyclic plastic deformation at high temperatures in nickel base superalloy Inconel 718.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The fact that companies are constantly subjected to changes creates challenges connected with constant learning and acquiring knowledge. Companies are forced to act in accordance with the generative strategy. Besides realizing the traditional tasks of production or service, companies need to acquire and process knowledge and apply it in practice. The consequence of these changes is the transformation of contemporary enterprises into knowledge-based organizations, with managers increasingly recognizing the role and importance of the concept of knowledge management in creating enterprises competitiveness. The main aim of the article is identification of knowledge management in production enterprises.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The author presents theoretical and practical considerations in which strategies of enterprise management in crisis situations will be presented. Therefore, two theses have been presented: 1. proper selection of the strategy in time of crisis is an element of enterprise success; 2. restructuring is part of the effective protection of the enterprise before the crisis. For this reason, a verification of views connected to the ways of managing in case of crisis seems reasonable. In addition, note that the board will decide whether a crisis in an enterprises is a threat to their functioning or it is an opportunity of management reconstruction process. These considerations will be presented in both, their theoretical and practical aspect.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The hereby article describes the study of two cases, the recruitment process as regards a newly created position and the decision concerning promotion to a managerial position. In both cases tool called Facet5 (used for measuring employees’ potential) was applied to support decisions connected with human resources. As far as the first case is concerned, the profile of an ideal candidate was established. Then the profiles of three candidates selected based on content were compared to the aforementioned profile of an ideal candidate. As regards the second case, the analysis of the strengths and weaknesses in the employee profile and comparing the benchmarks concerning the particular position confirmed the subjective assessments of the supervisors and contributed to making the right decision. The issues connected to the increasing significance of soft competences, talent management in organization and organizational culture in terms of employee effectiveness and corporate competitive were discussed as well. Analyzed situations indicate the potential value resulting from the usage of tools for researching employees’ potential.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">In Poland, one of the industries that has to take action to increase innovation is mining, as it is still a strategic branch of the Polish industry. The analysis of the structure of expenditure on mining innovation shows that there are innovations in the product sphere and solutions related to mechanical coal mining, while the sphere of widely understood management is omitted and expenditure on this field is negligible. Bearing in mind, among other things, the above challenges facing the Polish economy in the near future and in particular Polish coal industry, the author of the article attempted to analyse the most important challenges facing the mining industry in Poland. This article will attempt to answer the question in which direction innovative measures should be taken in Polish hard coal mining industry to allow for the development of this industry.</abstract>
