“…Ова легура се због тога назива псеудоеутектична. Сређеност великог домета у легурама система Pd-Ni није пронађена, док је сређеност кратког домета присутна на собној температури током изохроног жарења [16]. Магнетна трансформација почиње на страни Ni па све до Pd стране при константном смањењу температуре.…”

2Универзитет у Београду, Технички факултет у Бору,Бор, Србија Извод У овом раду датa је анализа тврдоће легуре PdNi5 након жарења, ради одређивања оптималних услова термо-механичког режима прераде. Варирани су температура и време жарења, а као одговор система посматрана је вредност тврдоће. Применом пуног факторског плана експеримента, типа 3 2 , и анализом добијених експерименталних података, дефинисан је математички модел функције одзива система који веродостојно описује експериментално добијене вредности (R 2 ˃ 0,95). Израчунати су ефекти главних варијабила а регресиона анализа је коришћена за фитовање одговора система.Кључне речи: PdNi5, експериментални дизајн, Pd катализатори-хватачи. НАУЧНИ РАД

The aim of this investigation was to determine the influence of the recrystallization temperature and recrystallization time on the microstructure and mechanical properties of the PdNi5 alloy subjected to cold deformation in the process of rolling at a constant deformation degree. The samples of PdNi5 alloy were recrystallization annealed within the temperature range of 200-1000ºC and annealing time range of 20-45 min after cold rolling with deformation degree of 97%. The tensile test was carried out using universal material testing machine. The hardness was also measured on the combined device for measuring Vickers and Brinell hardness. Metallographic observations were performed on an optical microscope. The analysis of the results of investigations regarding the microstructural changes and corresponding mechanical properties of cold-rolled PdNi5 strips shows that annealing temperature of 500ºC was sufficient to activate the energy for various recrystallization processes causing a change in the mechanical properties of cold-rolled PdNi5 strips. The annealing time, at constant annealing temperature, almost did not affect a recrystallization temperature and the mechanical properties of the cold-rolled PdNi5 strips.

Charcoal-supported palladium and nickel binary salt catalysts showed higher lignin gasification activity than the linear combination activities of the individual monometal catalysts, indicating a bimetallic synergetic effect. XRD and EXAFS analyses revealed that Pd–Ni alloy structures were formed during the lignin gasification over the catalysts, which provided higher activities for the gasification than the individual monometal catalysts.
