Rolling

Materials science; Metallurgy

The process of shaping metal by passing it between rolls revolving at the same peripheral speed and in opposite directions. In steel there are a number of different types of rolling mill for ...

Drilling

Materials science; Metallurgy

Drilling is a cutting process that uses a drill bit to cut or enlarge a hole of circular cross-section in solid materials. The drill bit is a rotary cutting tool, often multipurpose.

Forming

Materials science; Metallurgy

Forming, or metal forming, is the metalworking process of fashioning metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its ...

Mixed Dislocations

Materials science; Metallurgy

Dislocations in real materials are most commonly neither pure edge nor pure screw in their character, but are mixed dislocations whose Burgers vectors lie at an intermediate angle to the local ...

In the context of machining, a cutting tool (or cutter) is any tool that is used to remove material from the workpiece by means of shear deformation. Cutting may be accomplished by single-point or ...

Volume Defects

Materials science; Metallurgy

Volume defects in crystals are three-dimensional aggregates of atoms or vacancies. It is common to divide them into four classes in an imprecise classification that is based on a combination of the ...
