What type of Inconel material is it. The BRITE EURAM project BE4314 considered welding of IN625 (solid solution nickel base superalloy) and IN738LC (Precipitation hardened). IN625 is considered weldable, In738LC is not. Techniques included TIG, laser and EBW. As discussed above heat input is...

Martin you can't average von Mises stresses across material boundaries for two reasons. 1) At a fully bonded boundary it's the strains which are equal not the stresses. 2) You can't average von Mises stresses anyway, you have to average the individual stress components (x, y, z, xy, yz, xz)...

Hi all could anyone tell me specifically which direction is referred to by Azimuthal when talking about bore holes and wells Thanks

Al killing generally leads to smaller grain sizes owing to the effect of nucleation of more grains in the melt and the effect of Al particles pinning the grain boundaries helping to prevent grain growth. However, the strength benfits of the reduced grain size are offset by the lower fracture...

With reference to pipeline steels. Al deoxidizes steel by forming Al2O3 particles. These are very hard refractory particles which do not melt at steel forming temperatures and end up as inclusions in the steel. When it comes to forming the pipe the inclusions then act as both stress raisers and...

Fatigue occurs even if the material is only stressed in the elastic region. This is because fatigue damage occurs around microscopic stress raisers in the material, on a similar scale to the microstructure. Non metallic inclusions can be one source, or just dislocation pile up at a free surface...
