.... EDX analysis showed they consisted of niobium and fluorine. Plastic replicas, prepared by standard TEM techniques, were analyzed with selected-area electron diffraction, showing a pattern match for niobium tetrafluoride. Auger analyses showed electron spectra containing peaks representing carbon...

... Structure To examine the details of the pearlite structure, replicas were made at areas C and E and examined in a transmission electron microscope, Figures 15 and 16 . In area C, all of the pearlite patches were composed of long carbide platelets, freshly formed from austenite with no apparent...

... an energy-dispersive X-ray (EDX) detector on a scanning electron microscope (SEM). The results of this analysis are shown in Fig. 6 ; the major element in the spectrum was iron. The area analyzed is indicated by the arrow in Fig. 7 , which is a slightly higher-magnification view of the same cross section...

..., neither by optical microscopy or by scanning electron microscope (SEM). In the SEM, neither energy dispersive x-ray spectroscopy (EDX) nor the backscattered electron mode (BSE) revealed any traces of LME-causing foreign metals such as copper, zinc, lead, cadmium, mercury, indium, bismuth, tin, or others...

... examination of the MAR-M302 vane. Metallographic and EDX Analysis Figure 16 shows that the MAR-M302 vane was coated to provide protection against oxidation and hot corrosion [ 20 ]. It was interesting to note that the coating on the convex side of the vane had a uniform thickness of ∼0.11-mm over...
