Abstract:
The paper focus on possibilities of imaging microstructure changes in high strength low-alloyed carbon steel using an in-situ tensile stage placed in scanning electron microscope (SEM). The sample can be observed either in secondary electrons (SE) or by electron backscattered diffraction (EBSD). [..]

Abstract:
The microstructure and mechanical properties of high strength low-carbon steel, an austenitic stainless steel and the bimetallic semi-product produced from these steels were investigated. Two steels, an S700MC-type high strength low-carbon steel and a 316L-type austenitic stainless steel, were used as the layer materials for bimetallic semi-product, which was produced by electro-slag cladding. [..]

Abstract:
9 % Cr martensitic steels are perspective candidates for elements of boilers, steam pipes and tubes for novel fossil fuel power plants which are able to work at ultra-supercritical parameters of steam (T = 600 - 620 °C, P = 25 - 30 MPa). Crept structure and creep properties of 0.1С-9Сr-3Co-3W-VNbBN steel after creep tests at 650 °C under a stress of 100 – 220 MPa with a step of 20 MPa were studied. [..]

Abstract:
The paper presents results of studies on the crystallite sizes of oxide layer formed during a long-term operation on 13CrMo4-5 steel at an elevated temperature (T=470oC, t=190,000h). This value was determined by a method based on analysis of the diffraction line profile, according to a Scherrer formula. [..]

Abstract:
Electron beam (EB) welding of thick materials is not an easy task and finding the correct welding parameters and conditions is one of the crucial factors especially when the quality of weld root is required. The undesirable features of an electron beam weld can lead to premature failure or reduces the effectiveness of the resulting components (for example impellers). [..]

Abstract:
One method for evaluating the mechanical properties of components in operation is the use of methods that focus on the use of miniaturized test specimens. Basic properties used mostly for the service life evaluation are tensile strength, impact notch toughness or impact notch toughness transition curve, fracture toughness, creep and high cycle fatigue.

Abstract:
The intended operation time prolongation of the key components of fossil-fuelled power plants working in the creep conditions over 200,000 or even 250,000 hours (far beyond their original design lifetime) must be accompanied by thorough and extensive monitoring of the current material state and particularly creep damage. The extent of cavitation damage is routinely tested in-situ by using replica method and its quantification is based on a practice stated in VGB-TW 507, NORDTEST NT TR 170 or NORDTEST NT TR 302 that further develop the original Neubauer's classification.
