Generally something that is brittle will not deform, or deform very little before it breaks, where as something that is ductile will deform a lot before it breaks. That is how it is when comparing steels. White cast iron has no ductility therefore it will break with little or no deformation, where as mild steel has higher ductility and will deform considerably before it breaks.

What are examples of ductile rocks?
In order to be ductile a rock usually must be very hot. Rocks in lowest part of the crust and in the mantle (apart from the lithosphere) are usually ductile. Rock salt often exhibits ductile behavior as well.
Is a pencil ductile?
No, pencils are not ductile. Ductility refers to the ability of a material to deform under tensile stress. Pencils are made of graphite, which is a brittle material that breaks easily rather than stretching.
Is quartz ductile?
No, quartz is a brittle material, meaning it will fracture or break under stress instead of deforming. It does not exhibit ductility like metals or some polymers.
How does temperature and pressure affect brittle deformation and ductile deformation?
Temperature and pressure can affect brittle deformation by promoting the formation of fractures or faults in rocks under high pressure or temperature conditions. Ductile deformation is more likely to occur at high temperatures and pressures, leading to the rock bending and flowing rather than fracturing. Additionally, increasing temperature can enhance the ductility of rocks, making them more likely to undergo plastic deformation.
What is the difference between elastic deformation and ductile deformation?
Elastic deformation is reversible and occurs when a material is stretched but returns to its original shape once the stress is removed. Ductile deformation, on the other hand, is permanent and occurs when a material is stretched beyond its elastic limit, resulting in plastic deformation that changes the material's shape permanently.
Is stainless steel ductile or brittle?
it is ductile. For hardened stainless steel it gets less ductile, but not brittle.
Is silicon brittle or ductile?
Silicon has a Brittle-to-Ductile transition at around ~500 C.
Is ductile and brittle the same thing?
Ductile and brittle are NOT the same thing. In fact, almost the opposite.
Is silicon a ductile?
No, silicon is a brittle material and not ductile.
Can a rock unit be ductile and brittle?
Doubtful. Ductile by definition means "not brittle, easily stretched, malleable".
Is harder alloy steel is ductile or brittle?
brittle
Is fluoride brittle or ductile?
A fluoride salt is brittle.
Is sulfur malleable ductile or brittle?
Sulfur is brittle.
Does hardening of steel make it ductile or brittle?
more brittle
Is factor of safety of brittle material half of ductile material?
is factor of safety of brittle material half of ductile material
What is the differences between brittle and ductile fracture?
In brittle fracture, no apparent plastic deformation takes place before fracture. In ductile fracture, extensive plastic deformation (necking) takes place before fracture.
Are rocks nears earth's surface generally brittle or ductile?
They are generally brittle.
