Fig. 906 Tensile-overload fracture in a fracture-toughness specimen of 64Cu-27Ni-9Fe alloy that underwent spinodal decomposition during heat treatment for 10 h at 775 °C (1425 °F). The surface contains many intergranular facets with intervening regions of dimpled transgranular facets. See Fig 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. 1157 Portion of the tensile-overload fracture region of the fracture surface in Fig. 1156 , as seen at ten times the magnification there. (Structure is continuous α phase with dispersed β phase.) This displays a rather uniform size of equiaxed dimples, shows essentially no inclusions More

Fig. 3 SEM micrograph of a tensile overload fracture in a fracture toughness specimen of 64Cu-27Ni-9Fe alloy that underwent spinodal decomposition during heat treatment for 10 h at 775 °C (1425 °F). The surface contains many intergranular facets with intervening regions of dimpled More

Fig. 903 The surface of a tensile-overload fracture in a specimen of free-machining copper, showing large dimples. Scattered throughout the structure are particles of Cu 2 Te. The tellurium was added to the alloy to improve its machinability (the particles of telluride act as chip breakers More

Fig. 1083 Tensile-overload fracture in a specimen of a superplastic eutectic alloy containing 67% Al and 33% Cu. The material was cast, and the as-cast ingot was extruded at 430 °C (805 °F). Testing was performed at 0.025 mm/s (0.001 in./s) and at a controlled temperature of 450 °C (840 °F More

Fig. 1086 Tensile-overload fracture in a specimen of 67Al-33Cu alloy that was cast, extruded, and tested the same as the specimen in Fig. 1083 . In this specimen, the grain size is only 2 μm. It appears that both the large dimples and the CuAl 2 particles here are smaller than those in Fig More

Fig. 1159 View of the region of tensile-overload fracture in Fig. 1158 , at ten times the magnification there. (Structure is continuous α phase with dispersed β phase.) In spite of the effects of hydrogen, this region is quite similar in appearance to the tensile-overload region of the air More

Fig. 1165 Tensile-overload fracture surface of a notched specimen of titanium alloy Ti-6Al-4V heat treated to the same mechanical properties as specimen in Fig. 1162 and with a notched tensile strength of 1696 MPa (246 ksi). Crack nucleus is below center, at right. See also Fig. 1166 . 9× More

Fig. 530 Tensile-overload fracture in an unnotched specimen of AISI 8740 steel; tensile strength, 1351 MPa (196 ksi). A cup-and-cone fracture with a fibrous zone containing radial features between the central fibrous region and the shear lip. See also Fig. 531 and 532 . 9× More

Fig. 533 Surface of tensile-overload fracture in a notched specimen of AISI 8740 steel heat treated to a tensile strength of 2044 MPa (296.5 ksi). Fracture originated around the periphery of the specimen at the root of the notch. Radial features are evident. See also Fig. 534 and 535 . 9× More

Fig. 31 SEM images of ABS tensile overload fracture surface exhibiting ledges (red arrows). Tensile testing performed in ambient conditions at a crosshead displacement rate of 5 mm/min (0.2 in./min) (strain rate: 0.1 min −1 ) with a 10 kN (2250 lbf) load cell. Images taken at the fracture More

Fig. 45 (a) OM image of PVC tensile overload fracture surface with an inclusion. The specimen exhibited significant macro- and microductility during fracture. Macroductility is evidenced by the nonuniform cross section. (b) SEM image of matted and flattened fracture surface caused More
