Purpose: The paper presents the new neural networks model making it possible to estimate the hardness of continuously-cooled steel from the austenitizing temperature. Design/methodology/approach: The method proposed in the paper employs two applications of the neural networks of: classification and regression. Classification and consists in determining the value of dichotomous variables describing...
Purpose: Aim of this paper is to investigate the optical properties of soda-lime-silica (SLS) glasses which doped with different quantities of peanut shell (PS) powder. Design/methodology/approach: UV-Vis and Fourier transform infrared (FTIR) spectroscopy techniques are used to determine optical properties of glass. Findings: It was observed that the colorless and transparent pure SLS glass turned...
Purpose: The article characterises rhenium in terms of its physiochemical properties, most popular methods of manufacturing and key applications. The examples of rhenium at a nanometric scales are also presented, taking into account the latest literature reports in this field. The objective of the article is also to present advanced nanocomposite materials consisting of nanostructured rhenium permanently...
Purpose: The aim of the paper is to evaluate the dependence of microstructure parameters, strength and plasticity of steel on crack faces friction factor. Design/methodology/approach: The specimens for the investigation were cut out from the 10 mm thick hot-rolled plate of 65G steel used as a model material for fatigue and durability testing of whole-rolled railway wheels. The mechanical characteristics...
