In the paper the results of experimental research of the process of flow forming of cylindrical drawpieces were presented. The drawpieces were made of the 3.1 mm thick AMS 5596 sheet by drawing process. Tests were performed on two-roller metal spinning machine of a vertical axis Leifeld SFC 800 V500.The main purpose of this research was to determine the relationship between relative thickness reduction and the mechanical properties of tested material. Knowledge of these dependencies is especially useful in designing machines’ components manufactured by flow forming, in the selection of parameters of realization of this technological process as well. Mechanical properties were determined on the basis of uniaxial tensile of the micro samples obtained from the drawpieces: (I) after cold flow forming, (II) after cold flow forming and in-process heat treatment. Obtained results were shown graphically in the diagrams and their analysis was carried out. In addition, the microstructure of the sheet material tested after drawing and flow forming is presented.

Results of experimental investigations of metal spinning process of AMS 5504 sheets. cylindrical drawpieces with use of discs-shaped sheet with various diameter and thickness were shown in this work. Tests were performed on two roller metal spinning machine of a vertical axis Leifeld SFC 800 V500. The main objective of the study was to determine the dependence between limiting spinning coefficient, thin wall ratio coefficient and the fillet radius of forming rollers. To realize this aim required the development of an original methodology and experimental research plan. Determined relationship takes into account the occurrence of negative phenomena in the process of spinning such as wrinkling or cracking of material. Due to the possibility of prediction of these negative phenomena, determined relationship is used in the design of a metal spinning processes. On the basis on determined relationship can be done a practical assessment of the possibility of shaping with certain geometrical parameters by spinning. Obtained results were shown graphically on the diagrams and their analysis was carried.

Z uwzględnieniem zasad teorii agencji, teorii płacy proefektywnościowej oraz teorii kapitału ludzkiego przedstawiono wyniki badań dotyczące określenia stałych i zmiennych składników zarobków menedżerskich. Przedstawione badania na podstawie indywidualnych danych dotyczących wynagrodzeń menedżerskich w niemieckich przedsiębiorstwach dostarczyły zasadniczych informacji o przedsiębiorstwach, miejscach pracy i danych osobowych determinujących stałe i zmienne składniki płac menedżerskich. Analiza badań dostarcza zarządzającym zasobami personalnymi wskazówek do określania i optymalizacji składników płac menedżerskich.

In consideration of the principal-agent theory, the theory of efficiency wages as well as the human capital theory this paper investigates thoroughly the structure of the executive compensation. On the basis of individual compensation data of executives in Germany, we provide information on firm-specific, position-specific and employee-specific determinants of basic salary as well as performance- and benefit-related pay of executives. For the human resource management of firms the available regression analyses issue relevant indications regarding the optimization of management compensation.
