The data were also given that the total production in Croatia in 1990 was 2,500,000 tons of various metallurgical products (without cast iron products), and only 230,000 t in 2007, i.e. at the
1/7/2017· The high deposition temperature leads to the intensive inter-diffusion of silicon and carbon atoms and thus the formation of silicon carbides (810 cm − 1) occurs . E. Capelli et al.  demonstrated that a higher I D /I G ratio and a narrower ∆ G are associated with the carbon configurational changes from an amorphous mixture containing sp 3 /sp 2 configuration to a locally …
The magnetic and hyperfine properties of iron impurities in 3C- and 6H- silicon-carbide are calculated using the abinitio method of full-potential linear-augmented-plane-waves. The iron atoms are introduced at substitutional carbon, Fe C, and silicon, Fe Si, sites as well as at the tetrahedral interstitial sites with four nearest neighbours carbon atoms, Fe I (C), and four nearest neighbours
Cemented carbides for metal cutting appliions consist of more than 80% of hard-phase WC. Other important components are additional cubic carbonitrides, especially in gradient-sintered grades. The cemented carbide body is formed, either through powder pressing or injection molding techniques, into a body, which is then sintered to full density.
ture, University of Zagreb, Croatia. The original sample was stainless steel (BS 316S11, hardness: 160VHN) and it was Tenifer bath nitride at 5801C/4h (T-SS, hardness: 300VHN). Another SS sample was carbon steel (BS 060A62), vanadized at 9501C/4h (V-CS

1/6/2015· Silicon carbide (SiC) has been prepared successfully using concentrated solar energy provided by the IER-UNAM solar furnace. This has led to the development of a low CO 2 emissions process for the production of this material via carbothermic reduction of a silica/carbon (SiO 2 /C) nanocomposite, which has shown a more reactive carbon for formation of composite, being more …
