Fig. 13 A second-order polynomial fit of intensity versus concentration More

Fig. 14 Reversed-phase chromatogram of the product of the second step of the synthesis. More

Fig. 1 Comparison of dark-field light microscope fractograph (a) and an SEM secondary electron image (b) of the same area in an iron-chromium-aluminum alloy. Both 50× More

Fig. 15, 16 A second set of views, again at higher magnification, showing a fourth area of the surface of the low-cycle fatigue test fracture in aluminum alloy 7075-T6 in Fig. 13, 14 . This region of the fracture surface shows portions of two fatigue patches separated by a sizable step More

Fig. 19, 20 A second set of views at higher magnification showing another area of the stress-corrosion cracking fracture in aluminum alloy 7075-T6 in Fig. 17, 18 . Similar to the preceding set, this set of views shows a variety of grain surfaces resulting from intergranular rupture. The TEM More

Fig. 1227 TEM p-c replica at a second area of the facet at the arrow in Fig. 1225 , showing features resulting from transgranular cleavage and cleavage steps that cross a tilt boundary extending from lower right to upper left. The approximate direction of crack propagation was from lower left More

Fig. 835 Segment of a fractured second-stage gas-turbine wheel, cast from alloy 713C, that broke from fatigue in service. (About half of the disk portion of the wheel was never recovered.) The fracture origin (at arrow) was in a grinding-relief groove adjacent to the wheel-balancing pad More

Fig. 12 Heat-damaged turbine blades. (a) Heat-damaged first- or second-stage turbine blade (A), which remained intact but with a darkened appearance. It is common to have blades that appear to be in relatively good condition but with an underlying overtemperature condition. (b) Two third-stage More

Fig. 21 The DSC thermogram representing a second molding resin pellet that had produced brittle parts. The thermogram shows a major melting transition associated with nylon 6/12 and a weaker transition attributed to nylon 6/6. More

Fig. 24 A comparison of the second heating run results, further suggesting degradation of the failed sleeve material More

Fig. 45 Second-phase cleavage fracture in Ti-6Al-4V. (a) Light micrograph of polished and etched surface. (b) SEM of fracture surface. Source: Ref 10 More

Fig. 22 Micrograph of specimen shown in Fig. 17 . Cleaved second-phase particles are visible in the microstructure, and no debonding at second-phase/matrix interfaces is visible. Source: Ref 42 More

Fig. 2 The tip of the broken twistdrill. (a) End view. (b) Top view. A second drill from the same lot was also examined. There was carbide banding but to a significantly lesser degree. Hardness was measured as 63 to 64 HRC at both the flute edge and in the bulk of the drill. More
