Aluminium is a ductile metal, which means it possesses the ability for plastic flow with relative ease, which presupposes a relatively consistent and large plastic zone.
12.
Concepts such as the normality of plastic flow to the yield surface and flow rules for plasticity were introduced by Prandtl ( 1924 ) and Reuss ( 1930 ).
13.
Further, the growth of the plates must be accommodated by plastic flow in the surrounding austenite which is difficult if the austenite is strong and resists the plate's growth.
14.
They are also characteristically brittle because the directional nature of covalent bonds strongly resists the shearing motions associated with plastic flow, and are, in effect, broken when shear occurs.

An atomic force microscope image of an indent left by a Berkovich tip in a Zr-Cu-Al metallic glass; the plastic flow of the material around the indenter is apparent.
16.
By comparing maps of various materials, crystal structures, bonds, grain sizes, etc ., studies of these materials properties on plastic flow can be conducted and a more complete understanding of deformation in materials is obtained.
17.
It could be something to do with making sure the plastic flows nicely in the mould, but again, it doesn't look quite right for that . talk ) 08 : 26, 22 November 2016 ( UTC)

After the yield point, ductile metals undergo a period of strain hardening, in which the stress increases again with increasing strain, and they begin to neck, as the cross-sectional area of the specimen decreases due to plastic flow.
19.
In 1979 a report on the stability of the mine was released by a working group under HH Juergens, which describes an imminent scenario of uncontrolled plastic flow from the surrounding rock on the southern flank resulting in the subsequent loss of the load carrying capacity.

Adhesive wear is a common fault factor in industrial applications such as sheet metal forming ( SMF ) and commonly encountered in conjunction with lubricant failures and are often referred to as welding wear or galling due to the exhibited surface characteristics, phase transition and plastic flow followed by cooling.
