Theoretical basis and practical aspects of small specimen creep testing [PDF]
, 2013 Interest in and the application of small specimen creep test techniques are increasing. This is because it is only possible to obtain small samples of material in some situations, for example, the scoop samples that are removed from in-service components,

A Finnish nationwide register‐based study shows a further 50% decline in already low child mortality
Acta Paediatrica, Volume 113, Issue 12, Page 2643-2650, December 2024.Abstract Aim Child mortality declined significantly in Finland in 1969–2004. We investigated whether the already low mortality rate could still decline from 2005 to 2020. Methods This was a nationwide register‐based study. The subjects were children under 16 years of age who had resided in Finland between 2005 and 2020.

On the effects of friction modelling on small punch creep test responses: a numerical investigation [PDF]
, 2016 This paper shows the results of finite element (FE) analyses of Small Punch Creep Testing (SPCT) of a P91 steel at 600°C using two different approaches to model the friction between the specimen and the punch. The numerical results obtained by using the “

Weldability between steel type 304H and steel type P91 for high temperature applications
Zavarivanje i zavarene konstrukcije, 2023 This paper presents research about weldability between two dissimilar steels, martensitic steel P91 and 304H austenitic steel. Both materials are being preferred as a structural material for higher temperature applications due to their good mechanical properties at high temperatures.

Corrosion performance of different alloys exposed to HTL conditions—A screening study
Materials and Corrosion, Volume 75, Issue 10, Page 1258-1271, October 2024.Pre‐loading of C‐rings from material candidates with a strain gauge to achieve the desired yield strength. Exposure of these C‐rings to real HTL conditions (flowing, 390°C, 300 bars, black liquor, 18 days). Abstract The corrosion and material evaluation study in (a) water‐based simulated black liquor and (b) water‐based simulated black liquor at super ...

Effective determination of cyclic-visco-plasticity material properties using an optimisation procedure and experimental data exhibiting scatter [PDF]
, 2013 It may be inevitable in the design and analysis of most high temperature components (such as power industry pipe work) that variations in load and/or temperature will occur in normal operation.

Engineering Reports, Volume 6, Issue 9, September 2024.The review is in relation to coating materials that can withstand thermochemical cycle corrosive environments. The overall assessment is that very limited sets of coating‐substrate system are likely to survive for an extended period in the high temperature thermochemical environment. Recommended solution is to use special metals coated with metallic or

Influence of axial load on internal pressure creep of Mod.9Cr-1Mo circumferential welded pipe
Nihon Kikai Gakkai ronbunshu, 2015 Mod.9Cr-1Mo steel(P91) is widely used for high temperature pipes in ultra-super-critical thermal power plants. However it was recently reported that the creep damage was detected at heat affected zone(HAZ) in welded joints of the pipes so-called the ...

The fatigue crack growth behavior of hydrogenated 9Cr‐1Mo steel: An experimental and numerical study
Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 5, Page 1677-1695, May 2024.Abstract This research investigates the fatigue crack evolution in P91 steel through experiments and extended finite element method (XFEM) simulation for as‐received and hydrogenated conditions. Hydrogen pre‐charging is performed using a constant current electrochemical method in 1 M sulfuric acid solution.
