The axial pumps are used in a wide variety of applications, such as drainage control, power plants and process cooling. A fresh-water, vertical, axial-pump, stainless-steel impeller failed. The impeller was a single cast from stainless steel. A visual examination indicated that the fracture originat ...

This study presents a comprehensive investigation of the formation, composition and
behaviour of oxide layers during the high-temperature oxidation of four different steel alloys (16Mo3,
13Cr, T24 and P91) at a uniform temperature of 650 °C. The study is aimed at assessing the oxidation
damage du ...

creep-resistant steel;microstructure;carbide particle size;calculation of creep rate;creep activation energy;
Recent research has shown a dependence of the accelerated creep rate on the carbide particle distribution in martensite, with the creep rate depending on the number of carbide particles per unit of surface and their mutual distance. The aim of our work was to calculate the activation energy for diff ...

fatigue life;leaf spring;FEM simulation;spring steel;
A lifetime assessment of any component by performing classical fatigue tests on real geometry is a very expensive and time-consuming task. For this reason, many efforts have been made to produce a computer software which will be able to replace this conventional fatigue testing. Although there is so ...

When extruding the casted rods from EN AW 2011 aluminium alloys, not only their homogenized structure, but also their extrudable properties were significantly influenced by the hardness of the alloy. In this study, the object of investigations was the EN AW 2011 aluminium alloy, and the effect of ho ...

Welds are essential parts of tube systems in high temperature power works producing electricaql energy and have a heterogeneus microstructure due to the welding gradient of temperature and cooling rate. A short summary is given of findings related to the creep resistance of welds of creep resistant ...

The nucleation of M[sub]{23}C[sub]6 particles occurs on the surface of Fe[sub]{3}C particles with a high content of chromium. The initially high content of iron decreases and the chromium increases to about Cr[sub]{18}Fe[sub]{3}Mo[sub]{2}C[sub]6, in equilibrium with the in ferrite composition. The n ...

Structural fatigue is the major obstacle that prevents practical applications of the elastocaloric effect (eCE) in cooling or heat-pumping devices. Here, the eCE and fatigue behaviour of Ni-Ti plates are systematically investigated in order to define the fatigue strain limit and the associated eCE. ...
