Original scientific paper The properties of metallurgical cokes obtained in a laboratory from pure coal and with additives (light atmospheric residue of oil distillation and coal tar pitch) after heat treatment to 1600 °C were investigated. Changes in the basic characteristics (density, moisture, ash, metal and sulphur contents) were examined. Crystallographic parameters (crystallite size, Lc a...

Within the framework of a systems approach, the design of a high performance stainless steel integrated processing/structure/property/performance relations with mechanistic computational models. Using multicomponent thermodynamic and diffusion software platforms, the models were integrated to design a carburizable, secondary-hardening, martensitic stainless steel for advanced gear and bearing a...

Abstract The possibility of synthesizing tungsten carbide powders by carburizing mesoporous using ethanol as a carbon source is shown. WC was synthesized at the temperature 730-900 °C, argon or helium carrier gas in interaction with products thermal decomposition ethanol. Carbide has hexagonal crystal structure. specific surface area reaches 13 m 2 ⋅g −1 . Their average crystallite size determi...
