3D reconstruction was adopted to characterize the microstructural morphologies of Mg-3.0Nd-0.3Zn-0.6Zr alloy castings produced by high pressure die casting (HPDC) processes with different parameters, including low slow-shot speed, solidification pressurization and fast speed. At speeds 0.1 m·s−1, 0.2 m·s−1 0.3 porosity is concentrated in center one spiral staggered shape along liquid flow direc...

Fluid-induced seismicity in tectonically inactive regions has been attributed to fluid overpressurization of rock fractures during natural resource extraction and storage. We conducted a series triaxial shear-flow experiments on sawcut granite showed that the fracture responses can be dissimilar under various pressurization conditions. For pressure-controlled pressurization, uniform pressure di...

The purpose of this Commentary is to clarify as much possible the whole history reactor and containment pressure changes in Fukushima meltdown accident. It based on a new approach for film boiling, which kept after Zr-H2O reactions. Most important point that author applied boiling curve, basic theory phenomena, accident phenomena. As reaction rate proportional or under it increases r...
