Phase composition and microstructure of the doping alloy obtained by regenerative smelting of technogenic wastes were studied. This is necessary to determine technological characteristics that increase the degree of extraction of doping elements during th... see more


From economic and environmental points of view, solid phase chem­ical reactions are very important parts of modern chemistry and technology, enabling various processes to become cleaner, safer and easier to perform. This survey presents the basic concepts... see more

The paper reports a study into the physical-chemical properties of a doped alloy obtained from reduction smelting. That was necessary to identify the parameters that reduce the loss of Ni and Cr when processing oxide alloyed raw materials and utilizing th... see more

On the basis of experimental data the analysis of phase changes in intermetallic phases in alloys on the basis of zirconium (Zr – 1,03 ??.% Fe; Zr – 0,51 ??.% Fe; Zr – 0,51 ??.% Fe – ? (? = Nb, Sn,Ta) is carried out. We used experimental techniques:&... see more

Change in structural properties and phase composition of nanoparticles based on iron oxide was researched in the paper. As a result of conducted studies it was found that during heat treatment oxide phases of (?-Fe2O3) and a-Fe2O3 maghemite were formed in... see more

With the aid of DEFORM® software it is possible to conduct numerical simulation of workpiece phase composition during and upon heat treatment. The computation can be based on either the graphical representation of TTT diagram of the steel in question or o... see more

Real-time in situ neutron diffraction was used to characterize the crystal structure evolution in a transformation-induced plasticity (TRIP) sheet steel during annealing up to 1000 °C and then cooling to 60 °C. Based on the results of full-pattern... see more

This contribution showcases the interplay of several non-metathetic reactions (isomerization, silylation and “hydrogen-free” reduction) with metathesis in systems comprising a functionalized olefin and a soluble or resin-immobilized silane. These competin... see more
