(english) Appeaars like a series of waves and are created during rolling as a result of mechanical misalignment or cross-section irregularities in supply coil.
(english) Brittleness resulting from pickling steel in acid; hydrogen, formed by the interaction between iron and acid, is partially absorbed by the metal, causing acid brittleness.
(english) A change in position. A displacement may be a translation a rotation or a combination of those.
(english) A change in the shape of an object or material.
(english) Ductility generally refers to the amount of inelastic deformation which a material or structure experiences before complete failure. Quantitatively, ductility can be defined as the ratio of the total displacement or strain at failure, divided by the displacement or strain at the elastic limit.
(english) A saltwater solution for quenching or cooling when heat treating steel.
(english) Forces which hold an object together when external forces or other loads are applied. Internal forces are sometimes called resisting forces since they resist the effects of external forces.
(english) A cutting tool in which the tool bit,the boring bar and in some cases the tool holder are incorporated.
(english) The proportional constant between stress and strain for material with linear elastic behavior: calculated as stress divided by strain. Modulus of elasticity can be interpreted as the slope of the stress-strain graph. It is usually denoted as E, sometimes known as Young's Modulus Y, or E-Modulus.
(english) 1) Coating defect consisting of the formation of bubbles in a coating, which appear as hemispherical elevations. The blisters are hollow, and are usually caused by entrapped air or solvent. 2) A raised spot on the surface on the surface of metal due to expansion of gas which causes a subsurface metal separation such as inclusions and small laminations.
(english) A vessel, normally cylindrical, which is used to store gas for future release of the energy in the compressed gas to an accumulator.
(english) This word usually carries the same meaning as displacement, although it is sometimes used in place of deformation.
