The property of a metal which allows it to be permanently deformed, in tension, before final rupture Ductility is commonly evaluated by tensile testing in which the amount of elongation and the reduction of area of the broken specimen, as compared to the original test specimen, are measured and calculated
The property of a material by which it yields and continues to deform when a certain applied stress level is reached
The property of elongation, above the elastic limit, but under the tensile strength A measure of ductility is the percentage of elongation of the fractured piece over its original length
The property of a metal that enables it to be drawn through a die to form a wire
The measurement of a metals ability to bend or deform from stresses supplied by external forces before fracturing The measurement is defined by elongation and reduction of area performed on a tension test
That property of a material which permits of its being drawn out into a thread or wire
a measure of a material's ability to undergo appreciable plastic deformation before fracture E
Capacity of a material to deform permanently (e.g., stretch, bend, or spread) in response to stress. Most common steels, for example, are quite ductile and hence can accommodate local stress concentrations. Brittle materials, such as glass, cannot accommodate concentrations of stress because they lack ductility, and therefore fracture easily. When a material specimen is stressed, it deforms elastically (see elasticity) at first; above a certain deformation, called the elastic limit, deformation becomes permanent
(1) The ability of a material to deform plastically without fracturing, being measured by elongation or reduction of area in a tensile test, by height of cupping in an Erichsen test or by other means (2) The capacity of a material to deform plastically without fracturing (3) The property of metals that enables them to be mechanically deformed when cold, without fracture In steel, ductility is usually measured by elongation and reduction of area as determined in a tensile test
Ability of metals and alloys to retain strength and freedom from cracks when shape is altered
The ability of a material to deform plastically without fracturing, being measured by elongation or reduction of area in a tensile test or by other means
The ability of a substance to be drawn out or stretched thin While ductility is considered and important characteristic of asphalt cements in many applications, the presence or absence of ductility is usually considered more significant than the actual degree of ductility
The ability to permit change of shape without fracture In flat rolled steel, ductility is usually measured by hardness or mechanical properties in a tensile test
