Chevron marks in copper alloy?
Chevron marks in copper alloy?
(OP)
Hello everyone,
I have this fractured copper alloy shaft that shows what looks to me as chevron marks pointing to a single iniciation site. On SEM examination the mode of fracture observed was ductile overload. I have always associated chevron marks to brittle fracture. Is it possible to see this macro characteristic in the presence of a ductile fracture mechanism? Maybe I'm missing something here?
Best regards,
Gonzalo.

RE: Chevron marks in copper alloy?
The texture in the macro could be related to either the loading (just because it is ductile failure does not mean that it failed in a single overload) or the grain texture of the material.
