Opis:: The test of the results presented in this paper has demonstrated that the most suitable recrystallizing annealing temperature for cold drawn eutectoid steels is 700°C. The microscopic examinations, with the use of scanning electron microscopy and transmission electron microscopy and the results of mechanical properties tests have shown that only at this temperature it is possible to obtain the fully recrystallized homogeneous fine-grained structure of the pearlitic steel.

Opis:: Investigation of thermal stability of the alloy revealed stepwise crystallization process, manifested by two distinct complex exothermic peaks in differential scanning calorimetry curves. Kinetic parameters of individual crystallization steps were found using the Kissinger and Vyazovkin methods. Structural characterization of thermally treated samples showed formation of different iron-based phases including α-Fe(Si), Fe₂B, Fe₁₆Nb₆Si₇ and Fe₂Si and some metastable intermediary species. Morphology characterization of the surface and cross-section of the thermally treated samples showed granulated structure composed of several different phases and indicated occurrence of impingement effects during crystal growth. Value of estimated lifetime suggested very high stability against crystallization at room temperature and abrupt decrease of lifetime with temperature increase.

Opis:: Hyperthermia treatment is the heating of tumor tissue up to temperatures between 41°C and 45°C, which trigger several physiological reactions in the body. Hyperthermia within tissue can be applied through various mechanisms. One of them is magnetic hyperthermia which uses superparamagnetic iron oxide nanoparticles (SPIONs) heated by an externally applied magnetic field. SPIONs can also be used as sonosensitizers in ultrasound hyperthermia increasing acoustic wave attenuation. The impact of SPION concentration on thermal effect during ultrasonic and magnetic hyperthermia was investigated in agar-gel phantom with added magnetite nanoparticles. The presence of nanoparticles in the tissue-mimicking phantom increases the thermal losses of ultrasound energy and temperature of the phantom.

Opis:: Magnetic interactions between nanoparticles of magnetite $Fe_3O_4$ and α-Fe formed during calcination of ferrihydrite in $H_2$ at temperatures 533 ÷ 713 K were studied. The detailed phase analysis describes evolution of contents of magnetite and α-Fe. Explanation of an anomalous course of magnetic moment characterized by a local maximum at an early stage of formation of nanoparticles is discussed.
