Fig. 31 Fracture surface of notched tension test of alloy steel tested at 0 °C (32 °F). Fibrous overload fracture surface exhibits fine circumferential ridges. Similar markings have been erroneously identified as fatigue beach marks. Source: Ref 16 More

Fig. 16 Crack arrest lines on edge-notched tension specimens. Material thickness 13 mm ( 1 2 in.), 10 mm ( 3 8 in.), and 6 mm ( 1 4 in.). Note the distance for first arrest, which increases with section thickness, and note that the arrest lines are not closed More

Fig. 3 Scheme of a double-edge notched tension (DENT) specimen showing the inner fracture process zone (IFPZ) and the outer process dissipation zone (OPDZ). Adapted from Ref 34 More

Fig. 17 Crack-arrest lines on edge-notched tension specimens. Material thickness: 13 mm (½ in.), 10 mm (⅜ in.), and 6 mm (¼ in.). Note the distance for first arrest, which increases with section thickness, and note that the arrest lines are not closed along the centerline in the 13 mm More

Fig. 21, 22 Surface of a tension overload fracture in a notched specimen of annealed Ti-8Al-1Mo-1V alloy that was broken at room temperature. The tensile strength of the material was 1000 MPa (145 ksi). The fracture surface consists of dimples of various sizes, a few of which show some More

Fig. 1018 Tension-overload fracture in notched specimen of aluminum alloy 7075-T6. Notched tensile strength, 750 MPa (109 ksi); unnotched tensile strength, same as in Fig. 1015 . Surface is flat and coarsely fibrous. Considerable secondary cracking is evident, even at this low magnification More

Fig. 1244 Surface of a tension-overload fracture in a notched specimen of stress-relieved TZM alloy (Mo-0.5Ti-1.0Zr) sheet. Unnotched tensile strength was 972 MPa (141 ksi). The specimen was notched on each edge to a depth of 2.5 mm (0.1 in.) with a jeweler's saw and broken at room temperature More

Fig. 426 Tension-overload fracture in a notched specimen of AISI 4340 steel, heat treated to a hardness of 27 HRC and tested at −40 °C (−40 °F), showing a completely fibrous surface. See Fig. 427 and 428 for fractures in similar specimens tested at different temperatures. 17× More

Fig. 427 Surface of a tension-overload fracture in another notched specimen of AISI 4340 steel, the same as in Fig. 426 , but tested at −120 °C (−185 °F). Two distinctly different fracture-surface zones are visible; a fibrous zone, which originated at the notch, surrounds a radial region More

Fig. 428 Surface of tension-overload fracture in a third notched specimen of AISI 4340 steel, the same as those in Fig. 426 and 427 , but tested at 155 °C (−245 °F). At this low test temperature, a completely radial fracture was produced. The surface shows no fibrous zone, only radial marks More

Fig. 429 Tension-overload fracture in a notched specimen similar to those in Fig. 426 , 427 , and 428 , but heat treated to a hardness of 35 HRC. Tested at −40 °C (−40 °F). The surface shows only fibrous marks. See Fig. 430 and 431 for surfaces of fractures in similar specimens More

Fig. 430 Surface of a tension-overload fracture in a notched specimen of AISI 4340 steel the same as the specimen shown in Fig. 429 , but tested at 80 °C (−110 °F). A fibrous zone, which originated at the notch, surrounds a radial zone, which is off-center because of nonsymmetrical crack More

Fig. 431 Tension-overload fracture in a notched specimen same as in Fig. 429 and 430 , but tested at −155 °C (−245 °F). Even at this very low temperature, a small annular zone of fibrous fracture was formed next to the notch. Final fast fracture produced the radial marks in the central More

Fig. 460 Surface of a tension-overload fracture in a notched specimen of AMS 6434 steel sheet that was broken at 27 °C (81 °F), showing small equiaxed dimples. The heavy curved lines are intersections of dimple surfaces. See also Fig. 461 and 462 . TEM p-c replica, 2000× More

Fig. 461 Surface of a tension-overload fracture in a notched specimen of the same AMS 6434 steel sheet as in Fig. 460 , but broken at −73 °C (−99 °F). The dimples here are of the same size and nature as those in Fig. 460 . See also Fig. 462 . TEM p-c replica, 2000× More

Fig. 462 Surface of a tension-overload fracture in a notched specimen of the same AMS 6434 steel sheet as in Fig. 460 and 461 , but broken at −190 °C (−310 °F), showing a mixture of scattered dimples and (at arrows) cleavage facets. TEM p-c replica, 2000× More

Fig. 723 A typical tension-overload fracture in a notched specimen of 13-8 PH stainless steel with the same properties as those of the specimen in Fig. 720 . The fracture surface appears uniformly fibrous, with a hint of a shear lip. See also Fig. 724 . 9× More
