Abstract:
When dealing with corroded objects, it is necessary to identify the corrosion products to develop a proper treatment for this particular object. Using X-ray diffraction is still suitable to do the phase composition analysis of the material; however it does the analysis of the material in bulk. [..]

Abstract:
In this study, the impact of corrosion in S400 grade of reinforcing steel bar as for the mechanical performance on seismic loads (low-cycle fatigue LCF) was investigated. The mechanical performance and life expectancy of S400 grade of reinforcing steel bar on seismic loads was evaluated based on the strength degradation (reduction of maximum strength) during its loading time period, under corrosion or not circumstances.

Abstract:
Austenitization temperature of these steels can be used as a control measure of the transformation characteristics. Paper analyses the cavitation behaviour of a steel subjected to solution treatment at a lower temperature (950 °C), after which a primary aging at 700 °C and a tempering at 450 °C, were applied. [..]

Abstract:
This paper aimed to investigate the advantages of the use of S700MC steel instead of St52 steel widely used in industrial areas. For this purpose, a tensile test, a macro hardness test, a Charpy impact test, and a fatigue life test were performed on St52 steel and S700MC steel specimens. [..]

Abstract:
The effect of mean stress on fatigue life and fatigue limit was investigated for S355 NL+N ferritic-pearlitic steel. Changing stress ratio from R=0 corresponding to pulsating regime to R = -1, which is in conformity with alternating regime, the fatigue life was changed when applying the mean stress for the same stress amplitude.

Abstract:
This paper deals with the analysis of microstructure and mechanical properties of 9 Cr steel after austenitizing at temperatures of 1150 °C, 1180 °C and 1210 °C/2 hrs and after tempering at temperature of 790 °C/1 hr. Microstructure after austenitizing and quenching was formed of lath martensite and uniformly distributed ferritic area. [..]

Abstract:
A physical model describing the diffusion of interstitial atoms was developed and has been repeatedly used to study the redistribution of hydrogen, as well as predicting the risk of hydrogen damage during various real manufacturing processes.A particular advantage of this model is that, contrary to some simplified commercial and academic models, it contemplates diffusion in its most comprehensive description, i.e., with the driving force for atom diffusion being the gradient in chemical activation (and not simply occurring down a composition gradient). As the model also incorporates thermal history, microstructure, matrix solubility, multiple trapping distributions, interaction with the atmosphere and others, that is especially suitable to study of real manufacturing processes.In this case, two applications of interest both to academia and industry are presented.

Abstract:
The key characteristic of austenitic Hadfield´s steel is its toughening (hardening) under mechanical loading (during operation). By the influence of mechanical loading austenite transformed to martensite, resulting in surface hardening (curing) with a good toughness. [..]

Abstract:
Recent research by the steel industry focuses mainly on the high strength steels with excellent formability. A new look at the role of individual elements generally used for steels and the possibility of new metallurgical technologies application have led to the development of steels with a wide range of mechanical properties and formability used in automotive industry.

Abstract:
The high alloyed austenitic manganese steel, the Hadfield steel (C = 1.2 %, Mn = 12 %, Si = 0.45 %), thanks to its good wear resistance of the running surface and maintaining the high toughness of the internal material, is successfully applied for casted crossings. The crossings are the most dynamic stressed components in the railway turnouts. [..]

Abstract:
In this study, the quantity, size and type of non-metallic inclusions occurring in laser welded transformation induced plasticity (TRIP) and complex phase (CP) steel joints were identified using SEM and EDS techniques. Both steels include Al, Ti, and Si additions which are characterized by high chemical affinity to oxygen. [..]
