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. 26 Fracture surface of silicon nitride with machining flaw as origin. Specimen was tilted in the SEM showing the machined surface at the top and the fracture surface at the bottom. Machining flaw is aligned with grooves on the original surface. SEM; picture width ∼1 mm. Source: Ref 7 More

Fig. 10 Fracture surface of Si 3 N 4 with machining flaw as origin. Specimen was tilted in the SEM to show the machined surface at the top and the fracture surface at the bottom. Machining flaw is aligned with grooves on the original surface. SEM. 60×. Source: Ref 5 More

Fig. 31 Fracture surface of Si 3 N 4 with a machining flaw as the origin. Specimen was tilted in the scanning electron microscope, showing the machined surface at the top and the fracture surface at the bottom. Machining flaw is aligned with grooves on the original surface. Scanning electron More
