Both the steel loss to scale and the scale adhesion are very important parameters of the heating process. High values of steel loss (large thickness of the scale layer) reduce the heat exchange intensity in the furnace chamber, which results in higher energy consumption. a low adhesion value adversely affects the operation of heating furnaces, while too high value causes the scale to roll into a steel product and deteriorate its purity and quality. The paper presents the research methodology and the results of measurements of steel loss and scale adhesion. The effect of the excess air combustion ratio values on loss of steel and scale adhesion for constant furnace efficiency is discussed. This influence was described by mathematical dependencies. The tests were carried out for traditional technology and rational technology, enabling the reduction of steel losses to scale and energy consumption.

medIa Quenching technology requires the use of media with different cooling intensities and various shapes of cooling curves that show different particularities compared to that of conventional media such as water, oil, or emulsions. The use of synthetic quenching media is relatively new and also has multiple advantages such as non-flammability, safety in use and low cost. in this study, the cooling media tested was obtained by mixing 2 wt% carboxymethyl cellulose with 2 wt% Naoh in one litter of water. Moreover, three different temperatures (20°C, 40°C and 60°C) of the quenching media were evaluated. By dissolution in water, a synthetic solution with low viscosity, surfactant and lubricant was obtained. Because carboxymethyl cellulose is a biodegradable organic material, that is obtained as a by-product in the manufacture of paper, a basic substance with a preservative effect was added. according to this study, both the variation diagram of the heat transfer coefficient and the diagram of the cooling rates, during the cooling stages give important indications regarding the use of a liquid cooling medium for quenching.

In the present study, the evolution of different failure mechanisms in carbon fiber reinforced polymer composites is being investigated using acoustic emission technique, unsupervised clustering technique and improved b-value analysis. The experimental part involved the realization of tensile tests of different materials, namely samples with [0/90] 2S uniaxial layer configuration and [0/90] 2S twill fabric samples. Both types of tests were monitored using one wideband acoustic emission sensor, while the tensile tests of twill fabric samples were additionally supplemented with resonant acoustic emission sensor to perform a comparative analysis between datasets from resonant/wideband acoustic emission sensor. The comparative study itself was preceded by the failure mechanisms characterization process, which has been performed on the tensile test dataset of [0/90] 2S layer configuration with the contribution of clustering technique. The subsequent analysis of the twill fabric resonant/wideband acoustic emission sensor datasets included the improved b-value technique, which relates the magnitude of fracture with the slope of the amplitude distribution. The presented results, especially in terms of the improved b-value technique applied to individual clusters, show enhanced ability to assess in more detail the actual structural integrity depending on the applied load.

the article presents a precise method for the orientation process of niMnGa-based single crystals. For this method, a scanning electron microscope equipped with an eBSD camera and a heating stage allowing temperatures exceeding 873 k was used. the orientation process was carried out in both the high-temperature austenite phase and in the room-temperature martensite phase. the facilities allowed for determining the orientation of a single grain of austenite at elevated temperatures as well as the orientation of particular martensitic variants at room temperature. A practically perfect cubic orientation was obtained in the austenitic case with a deviation of about 1° while the samples oriented in the martensitic phase deviated from the desired orientation by 4.5-5.2°. Additionally, the training process of single crystals was carried out in order to show the influence of the orientation process on twinning stress.
