Twinning

Materials science; Metallurgy

A process in which two or more crystals, or parts of crystals, assume orientations such that one may be brought to coincidence with the other by reflection across a plane or by ...

Necking

Materials science; Metallurgy

The reduction in diameter that occurs as a sample material is subjected to tensile stresses. Necking, in engineering or materials science, is a mode of tensile deformation where ...

Clevage

Materials science; Metallurgy

Cleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism.The degree of deformation and ...

Fracture

Education; Knowledge

A fracture is the separation of an object or material into two, or more, pieces under the action of stress.The fracture of a solid almost always occurs due to the development of ...

Fatigue

Materials science; Metallurgy

The concept of fatigue is very simple, when a motion is repeated, the object that is doing the work becomes weak. For example, when you run, your leg and other muscles of your ...

Porosity

Materials science; Metallurgy

Solid materials have pores in them, sometimes these pores are almost microscopic in size, and sometimes they're very visible. Porosity is a measure of how much air or liquid ...
