Abstract: The microstructure of initial Nd-Fe-B alloy has the substantial effect on the processing and the hysteretic properties of sintered Nd-Fe-B-based magnets. This work is aimed at the structural characterization of the strip-cast Nd-Fe-B alloy, which will be used as the matrix alloy for the preparation of magnets with variable set of functional parameters via the application of REM hydrides or hydrogenated REM compounds added to the powder mixture and using processes of grain boundary diffusion and grain boundary structuring.

Abstract: The gas-atomized powder prepared from AE42 magnesium alloy was mechanically milled at various conditions. The effect of milling on the size, morphology and particle microstructure was investigated. [..] Read more

Abstract: The influence of severe plastic deformation on ongoing phase transformations in metastable β-Ti alloy Ti15Mo was investigated in-situ during linear heating by electrical resistance and complemented by ex-situ microstructure observations using transmission electron microscopy. Several non-monotonic regions in the temperature dependence of electrical resistance were identified and associated with corresponding phase transitions, namely the reversible diffusionless shuffle transformation of athermal ω phase, followed first by diffusion controlled growth of isothermal ω phase and subsequently its continuous dissolution.

Abstract: Two experimental magnesium alloys containing neodymium and zinc (Mg-5Nd-1Zn and Mg-1Nd-1Zn) were processed by severe plastic deformation (SPD) method - equal channel angular pressing (ECAP). The effect of SPD processing on the microstructure was studied by light microscopy (LM) and scanning electron microscopy (SEM) including electron backscatter diffraction (EBSD). [..] Read more

Abstract: The report presents results of the analyses of biocompatible WE 43 Mg-based alloy processed by friction stir processing (FSP) at two different rotational speeds of 400 rpm, and 1200 rpm. The structures were observed by scanning electron microscopy (SEM), electron backscattered diffraction (EBSD). [..] Read more

Abstract: In the present work Al4Cu-SiC composites were fabricated in a rigid die on a single-action compaction press and then sintered under the nitrogen atmosphere. The SiC (< 2 µm) content was 5 and 10 wt%. [..] Read more

Abstract: Imposing large plastic deformation by SPD processes such as ECAP, HPT, ARB etc. in a relatively simple way enables to obtain material with high grain refinement. [..] Read more

Abstract: The paper determines the influence of presence of various manganese content (0.2; 0.4 and 0.6 wt%) on the course of the crystallisation process, mechanical properties and structure of alloy AlSi10Mg. Recycled secondary materials with elevated content of iron were used to prepare the cast of this silumin. [..] Read more

Abstract: The article analyzes the approaches of different authors to understanding the essence of the term "customer-oriented". Based on the McKinsey "7C" model, various aspects of the client-oriented approach are demonstrated. [..] Read more

Abstract: At the end of 2018, the unemployment rate in the Czech Republic was at its minimum for the last twenty years and the same applies within the framework of the EU member countries. Although being favourable in social terms, for companies this situation brings about large difficulties because they are unable to obtain qualified labour force, while costs connected with its finding and maintaining grow rapidly.

Abstract: The article deals with the acquisition of character positions from the input image and with modifications to increase the accuracy of recognition that precedes it. As the input image is meant a camera output or a photo of text information in the surface on different types of blanks. [..] Read more

Abstract: At present, climate change, sustainability, resource use and greenhouse gas emissions are issues that cannot be avoided. Undeniably, the impact of human activity unbalances many natural processes and it is producing effects on the planet's climate, ecosystems and people's health that are unprecedented.If we look into CO2 emissions, industry produces about one third of non-agricultural emissions, and of that, more than half is due to materials production (mainly steel and cement).

Abstract: The article deals with quality analysis of power grids especially in metallurgical industry when using large engines, arc furnace, induction heating and so on. Nowadays, these non-linear loads which are connected to power grids cause heavy disturbances, which can cause big problems like damage or even destruction of machines or devices connected near the point, where disturbances occur.

Abstract: The main topic is to find energy cost saving item and implementation method in the pretreatment process at the paint production plant. The paper presents explanation of experiment with temperature reduction and its influence on the quality and steam consumption. [..] Read more

Abstract: The paper introduces modifications to the classical regression analysis that are deemed necessary when working with typical data from metallurgy, and foundry industry in particular. It specifically concerns the problem of multicollinearity, and shows both the practical application of the modified procedures and its consequences. [..] Read more

Abstract: Ribbed bars, like other metallurgical products, must meet the relevant requirements resulting from standards and specified by customers in their orders. The following dimensions of ribbed bars are specified in the standards: nominal diameter and their permissible deviations, mass range of 1 m of ribbed bar, core diameter, rib height, width and length of ribs longitudinal. [..] Read more

Abstract: This article aims to survey and evaluate the current state of the heating furnace and to analyze the operational data using data mining tools and artificial intelligence in order to capture the complex weaknesses of the current system and to propose those modifications that would allow deployment model management levels in its entirety.
