Abstract Scope |
The ductile fracture of a type 65/35 alpha brass tested in tension at room temperature has been studied inside the ultra-high vacuum chamber of an Auger/scanning/micro-probe equipment. The fracture characteristics of small specimens tensile deformed in especially designed apparatus were registered in terms of the morphological aspects and quantitative participation of elements. It was observed that the ductile fracture is associated with ZNS inclusions separated from the Pb rich alloy interface. Regions without inclusions but with Pb segregation are possible sites favorable to the fracture propagation.
