The appearance of surface of ductile fracture will be ___________

The appearance of surface of ductile fracture will be ___________ Correct Answer grey and fibrous

The ductile fracture occurs by gross deformation before fracture, which gives it a fibrous structure; the surface is not flat, causing its dull appearance.
