are higher than those in the Zr layer during the hot-rolling bonding process. Based on the EDS results (Fig. 2), the interface layers are relatively thin (~10 μm). However......
. The sintering was performed under vacuum with a constant compression pressure of 40 MPa. Thin graphite foils were placed between the powders and the graphite die to ensure easy removal of the sintered... Teneo low-vacuum scanning electron microscope (LVSEM) and an FEI Talos F200X STEM equipped with a Super-X silicon drift detector (SDD) energy-dispersive X-ray spectrometer (EDXS) system. Thin-foil TEM......

. Tests have been performed to use lower-powered CW and pulsed CO2 lasers to cut thin plates of granite, marble and limestone [107-110]. They found that maximum cutting speed obtained increases... mechanism among rock, laser and purge gas The interaction mechanism of laser, rock and purge gas is to be further investigated. Tests should be performed on thick rock blocks rather than thin plates......
by the carbon film and copper grid net that were used during characterization. The Na present on the spectrum was there to verify if the coating was composed of Na-jarosite (NaFe3(OH)6(SO4)2). However......
. The gas phase moves forward in the shape of a columnar. The liquid phase is distributed in the form of a liquid film on the inner wall of the pipe as a result of the existence of centrifugal force......
