TiN and Ti2O3 are the predominant inclusion types in Ti-alloyed ferritic chromium stainless steels. In order to ensure the required steel cleanness level, an effective removal of such inclusions in the slag during secondary metallurgy is essential. This inclusion removal predominantly takes place via dissolution of the inclusion in the slag. The dissolution behavior of TiN and Ti2O3 in CaO-SiO2...
Zinc represents the most effective and economic corrosion protection especially for steel base materials. Improved corrosion resistance can be achieved by alloying zinc with small amounts (around 1 Yo) of transition metal elements like Co, Ni and Fe. Zn-Fe and Zn-Co alloys containing up to 1.5 Yo of the transition metal were plated using an alkaline and acidic electrolyte respectively. Zn-Ni al...
This paper investigates the manipulation of chemical composition a laser weld by dissimilar filler material and its effect on residual stress. The aim is to minimize stresses in seam. In order negate stresses, combinations low-carbon manganese steel (S235JR) base with high-alloyed solid wires (G19 9 G25 20), as well similar low-alloyed wire G3Si1 are analyzed. goal show that so-called low-trans...
The present work is devoted to the study of influence parameters structural anisotropy rolled products on low-temperature impact strength alloyed steels. A quantitative metallographic analysis microstructure steel samples obtained after testing for toughness was carried out. It established that main reason decrease in a highly developed segregation band enriched with carbon films formed at stag...
A tunable structural engineering of nanowires based on template-assisted alloying and phase segregation processes is demonstrated. The Au-Ge system, which has a low eutectic temperature and negligible solid solubility (<10(-3) atom %) of Au in Ge at low temperatures, is utilized. Depending on the Au concentration of the initial nanowires, final structures ranging from nearly periodic nanodisk p...
