Abstract:
The subject of this study is the temperature stability of a microstructure in X37CrMoV5-1 hot-work tool steel.
Conventionally treated by quenching and high-tempering this steel is used for tools working at temperature up
to 550 °C. [..]

Abstract:
The work deals with fractal response study of root of the TH29 profile from carbon steel micro-alloyed with vanadium (0.12 %), niobium (0.04%) and nitrogen (0.012 %) designated for mine supports. The profile was evaluated both after hot rolling and after subsequent straightening that showed different impact energy values, even when the feature of fracture surfaces did not differ significantly.

Abstract:
The corrosion resistance of three grades of valve steels (X33CrNiMn23-8, X50CrMnNiNbN21-9,
X53CrMnNiN20-8) in combustion gases of propane-butane (LPG) under thermal shock conditions has been studied. It was stated that X33CrNiMn23-8 steel, containing highest concentration of chromium and nickel and
also the lowest of manganese concentration, showed the best corrosion resistance in comparison to another
tested steels. [..]

Abstract:
The project MPO FR-TI3/458 "Material solutions for industrial equipment working with ultra-preheated steam",
is focused on the assessment and prediction of long-term creep life of heterogeneous and homogeneous weld
joints of the selected materials that can be used for superheaters and re-heaters of newly built or refurbished
power plant boilers. The acquisition of detailed and reliable information, especially about the behaviour of weld
joints exposed to high temperatures and pressure during long-term operation is of vital importance. [..]

Abstract:
The balance between strength and toughness of supermartensitic steels can be controlled by heat treatment parameters. Quality heat treatment usually consists of quenching and single or double tempering above the
Ac1 temperature. [..]

Abstract:
In the automotive industry about 60% of mass of the car continue to represent structural elements, formed of
steel plates of increasing strength while maintaining good plastic characteristics and susceptibility to stamping.
Constructors seek to reduce the mass of cars and semi-trailers and it is possible through the use of fine-
grained and quench and tempered high strength steels. [..]

Abstract:
In recent years, the intensive research work has been carried out on the development of heat treatment which allowed obtaining carbide-free microstructures with retained austenite. These include the quenching with isothermal annealing (austempering) leading to obtain a nanocrystalline bainite [1,2] and Quenching&Partitioning (Q&P) [3] leading to obtain a microstructure composed of carbon-depleted martensitic matrix and carbon-enriched retained austenite.

Abstract:
Fatigue in Cr-Mo steel, JIS SCM435, candidate for use in fuel cell vehicles is investigated at different test frequencies in two groups of hydrogen charged and uncharged specimens under tension-compression fatigue and stress ratio R = −1. Specimens are machined in hour-glass shape with artificial hole from which initial cracks start their propagation. [..]

Abstract:
To control the spread of pathogens in hospital environments, good hygienic routines based on cleaning and disinfection of surfaces contaminated with biological materials, are obligatory requirements. Ambulance transporting patients with infectious diseases may often be contaminated because of the special construction and the narrow space inside, ventilation system, and all the devices present.
