Two-dimensional Defects

Materials science; Metallurgy

The two-dimensional defects that appear in crystals can be usefully divided into three types: free surfaces, which are the external surfaces at which the solid terminates at a ...

Forging

Materials science; Metallurgy

In metallurgy, the process of shaping metal and increasing its strength by hammering or pressing. In most forging an upper die is forced against a heated workpiece positioned on a ...

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 ...

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 ...

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 ...

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 ...

Cutting

Materials science; Metallurgy

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 ...
