Fig. 112 Example of a fractured wedge test specimen used to assess the carbide stability in a cast iron melt. Note the change in fracture appearance in the tip (white fracture due to the presence of carbide) compared to the base of the wedge (dark due to the presence of graphite). Actual size More

Fig. 166 “Cup and cone” tensile fracture of cylindrical test specimen is typical for ductile metals; in this case, annealed AISI 1035. Fracture originates near the center of the section with multiple cracks that join and spread outward. When cracks reach a region near the surface, the stress More

Fig. 904 Fracture surface of an underaged fracture-toughness test specimen of Cu-2.5Be alloy that had been aged for 1 1 2 h at 260 °C (500 °F) prior to being tested in air. Tensile strength was 930 MPa (135 ksi). Fracture was transgranular and produced the wide variety of dimple More

Fig. 905 Fracture surface of a fully aged fracture-toughness test specimen of Cu-2.5Be similar to that in Fig. 904 , but aged 3 h at 315 °C (600 °F) before being tested in air. Tensile strength was 1240 MPa (180 ksi). The dimples on the transgranular facets are much finer than in Fig. 904 More

Fig. 908 Tensile-overload fracture in a fracture-toughness test specimen of the same 64Cu-27Ni-9Fe alloy as in Fig. 906 , but here spinodal decomposition occurred during heat treatment at 775 °C (1425 °F) for 100 h. Only dimpled transgranular facets are visible (no intergranular facets More

Fig. 909 Surface of the fracture in a fracture-toughness test specimen of the same 64Cu-27Ni-9Fe alloy as in Fig. 906 , 907 , and 908 , but which was heat treated at 775 °C (1427 °F) for 200 h. Very fine dimples can be seen among the larger ones. The large cavity at the center of this view More

Fig. 945 An overload fracture in a miniature tensile-test specimen cut from the fitting in Fig. 938 , displaying the same type of cellular surface structure produced by the service fracture. See also Fig. 946 . SEM, 300× More

Fig. 949 Surface of a fracture in a miniature impact-test specimen cut from the broken aluminum alloy 356.0-T6 bell-crank fitting shown in Fig. 938 . The appearance here is very similar to that of the service fracture in Fig. 939 . SEM, 60× More

Fig. 950 View of the fractured test specimen in Fig. 949 , but at another location. The appearance here is quite similar to that of the service fracture in Fig. 943 . SEM, 300× More
