Abstract:
Depth sensing indentation allows deriving mechanical properties from the indentation load-displacement data using a micromechanical model developed by Oliver & Pharr (O&P). However, O&P analysis on the indentation unloading curve is developed from a purely elastic contact mechanics (sink-in). [..]

Abstract:
Carbon diffusion was studied in temperature interval 573 - 1073 K in carbon-supersaturated surface layer of 9Cr–1Mo steel P91 and in model Fe-15Cr binary alloy. Extremely low carbon diffusion coefficient D (by 3 orders of magnitude lower than the value Deq in material with equilibrium carbon concentration) was observed in carburized surface region of Fe-15Cr.

Abstract:
The phase transformations which occur in 38CrAlMo6-10 steel were analysed at various temperatures, particularly in the intercritical Ac1-Ac3 region, by means of computer simulations and by dilatometric tests. In the study, the effects of heat treatment conditions in the intercritical region on the martensitic and bainitic transformations and on the Ms temperature were investigated. [..]

Abstract:
This paper deals with welded joints carried out by 111 (MMAW) and 141 (GTAW) welding method on the P92 steel. With respect to the small size of each region in the heat-affected zone (HAZ), the suitable simulation technique for estimation of the microstructure and properties needs to be prepared. [..]

Abstract:
This paper focuses on the influence of the cold bending process on stress -strain characteristics of materials SUPER304H, HR3C, Tp347HFG that can be used for superheaters and reheaters of newly built or refurbished power plant boilers.The qualification tests were carried out on bends in two dimensions of tubes and on several bending radii to verify the effect of cold bending technology. In the year 2013 was tested new bend radius. [..]

Abstract:
Supercritical water (SCW) is a promising medium with a broad spectrum of potential applications in the
industry. However, the absence of appropriate structural material able to withstand the severe corrosive
conditions of SCW still limits its utilization. [..]

Abstract:
One of the available routes to developing a new material resistant to high-temperature creep is to create a
microstructure consisting of a metal matrix and dispersed stable particles. For making intricately shaped
components from such materials, new processes must be found to allow near net shape products to be
manufactured in a simple and rapid manner. [..]

Abstract:
The corrosion resistance of widely used X50CrMnNiNbN21-9 high-alloyed austenite valve steel, in three
different combustion gases have been compared. The comparison was performed on the basis of results
of kinetic corrosion of the tested steel in combustion gases from propane-butane, gasoline with 5 and 10 %
of ethanol additives (v/v) and fuel oil with 5 and 10 % of FAME additives (v/v). [..]

Abstract:
The results of studies of the influence of intercritical annealing parameters on the austenite formation and its
stability in TRIP steel (0.41 % C, 1.52 % Mn and 1.22 % Si) were presented in the paper. Based on the results
of a dilatometric analysis and metallographic investigation it was noted that the pearlite to austenite
transformation does not occur at a constant temperature, which is referred to as Ac1, but rather within certain
- possible to determine - temperature range which is enclosed within Ac1s and Ac1f values. [..]

Abstract:
The development of fatigue cracks is often analyzed on the basis of their geometry and is explained merely by
the state of tensions, without the consideration of the microstructure. The crack resistance is, however, strictly
connected with the microstructure. [..]

Abstract:
The physical and chemical reactions that occur in the process of steel melting and solidification produce non-
metallic compounds and phases, referred to as inclusions. The quantity of non-metallic inclusions is correlated
with the content of tramp elements in the alloy, while their phase composition and structure, in particular shape,
dimensions and dispersion, are determined by the course of metallurgical processes. [..]
