Opis:: The article presents the results of tests carried out on the manufactured composite materials based on a two-phase NiAl/Ni₃Al matrix, which was enriched with the addition of TiB₂ ceramic particles added in an amount of 4 and 7 vol%. The resulting mixtures were sintered by the High Pressure High Temperature (HP-HT) process. The results were compared to the results obtained for the sole matrix material produced under the same conditions. It has been shown that, at a lower density, the addition of reinforcing particles increases the composite hardness, Young’s modulus and resistance to frictional wear. However, higher addition of TiB₂ (7 vol%) was observed to yield less satisfactory results, and despite higher hardness and lower density caused a decrease in other properties tested. The produced materials were characterized by a compact and highly differentiated microstructure free from any noticeable cracks and pores.

Opis:: The paper presents the results of studies on the effect of nonuniform temperature distribution over the length of feedstock on the variation of longitudinal stresses in the rolling direction and band dimension change during the continuous rolling process. The studies were performed based on actual engineering data for a 160x160 mm square cross-section feedstock of steel S355J0. Numerical modelling of the rolling process was performed using Forge 2008®, a finite-element based computer program. Thermovision measurements and bars geometrical dimension changes were carried out in a domestic steelworks.

Opis:: The aim of the work was to investigate the influence of temperature on the rate of copper removal from the obtained slag from the flash direct-to-blister process by means of a carbon reducer. The slag used in this work was taken from the direct-to-blister Outokumpu flash furnace at the smelter in Głogów, and graphite penetrators were used as the slag reducers. The experiment was carried out at 1573 K, 1623 K and 1673 K. It was found that the rate of the de-coppering process of the “Głogów” slag increased with the increase of temperature.
Celem pracy było określenie wpływu temperatury na kinetykę procesu odmiedziowania żużli z procesu zawiesinowego za pomocą reduktora węglowego. Do badań użyto żużel pobrany z procesu zawiesinowego realizowanego w HM „Głogów”, przy czym reduktorem były penetratory grafitowe zanurzane w badanym żużlu. Badania przeprowadzono w temperaturach 1573 K, 1623 K i 1673K. Uzyskane wyniki wskazują, że szybkość procesu zwiększała się ze wzrostem temperatury ale tyko w pierwszym okresie.

Opis:: Fe-Cr-Al based Powder porous metals were manufactured using a new electro-spray process, and the microstructures and high-temperature oxidation properties were examined. The porous materials were obtained at different sintering temperatures (1350°C, 1400°C, 1450°C, and 1500°C and with different pore sizes (500 μm, 450 μm, and 200 μm). High-temperature oxidation experiments (TGA, Thermal Gravimetry Analysis) were conducted for 24 hours at 1000°C in a 79% N2+ 21% O2, 100 mL/min. atmosphere. The Fe-Cr-Al powder porous metals manufactured through the electro-spray process showed more-excellent oxidation resistance as sintering temperature and pore size increased. In addition, the fact that the densities and surface areas of the abovementioned powder porous metals had the largest effects on the metal’s oxidation properties could be identified.

Opis:: The paper presents the results of theoretical studies influence of non-uniform temperature distribution along the feedstock length to the unit friction force working on the metal contact surface with the roll change during the round bars 70 mm in diameter continuous rolling process. This value is one of the major factors affecting the grooves wear during the rolling process. The studies were carried out based on the actual engineering data for 160 × 160 mm square cross-section feedstock of steel S355J0. Numerical modelling of the rolling process was performed using Forge2008®, a finite-element based computer program.
