... samples and wide gap samples containing IN-738 additive alloy. All fatigue failures in the brazed samples occurred in the braze joints. An analysis of the fracture surfaces using a scanning electron microscope revealed that porosity was the major contributing factor to fatigue failures in the wide gap...

... surface area of the calcined samples, and the degree of carbonation. It was observed that the higher the calcination temperature, the lower the sorbent reactivity. The Brunauer–Emmett–Teller measurements and scanning electron microscope images provided quantitative and qualitative evidences to prove...

... was maroon in color and was caused by the reaction and spreading of the V 2 O 5 . Coatings were studied using a scanning electron microscope (SEM) and x-ray diffraction (XRD) techniques. To characterize the changes in microstructure during the hot corrosion tests, polished cross...
