.... The embrittled tube was then analyzed using an Auger electron scanning microprobe. A notched sample was fractured under ultrahigh vacuum. Tellurium and carbon, along with oxygen, copper, and nickel, were detected on much of the intergranular fracture surface. Scatter maps, showing the location of tellurium...
