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 rotation about an ...

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 relatively large ...

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 metamorphism along with ...

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 certain displacement ...

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 body become weak, not ...

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 can be absorbed by ...
