That's a cool fracture surface. While some ductile fracture surfaces have a nice axial symmetry to them, with a fairly flat crack on the outside, this seems to have some clear indications of shear failure (failed at max shear, 45 degree lines)
actually, the yield is before the necking, its the point at which the material first "gives in" to the stress, stretching out permanently. its not until a considerable further load is applied that it reaches the point where necking, and complete failure happens

I could be wrong, though.

that's just brittle.

i think there is no any yeld zone very ductile small diametre before made a necking.
my comment : test is not pass.

Seconded.
Ductile materials have a plastic region (or permanent deformation.)
Brittle materials fail at yield.
