A research apparatus was designed for use in an investigation to compare the current conduction and wear behavior of metal fiber brushes on commutators and slip rings. To this end, metal fiber brushes were operated, while conducting direct current, o

“Regular” deformation banding is distinguished from several other types of bands caused by plastic deformation. It is observed mainly in homogeneous f.c.c. and b.c.c. metals. It is common in wavy glide materials up to about T M /2 deformation tem

An overview of the low-energy dislocation structure (LEDS) theory of low-temperature, that is non-creep, dislocation-based crystal plasticity is presented, as systematically developed over the past 35 years. It is ultimately based on G. I. Taylor's 1

In compressed samples of high-purity aluminum alloys, without (Al–0.5 wt% Cu) and with hard precipitates (Al–0.5 wt% Cu–1.0 wt% Si), a variety of deformation band patterns has been observed, including occasional exquisite detailed structuring.

Very dense dislocation networks overlying grain boundaries in extruded and cold-deformed MA aluminium alloys, in the asreceived or annealed condition, have been identified as dislocation rotation boundaries which accommodate relative misorientations

The microstructural evolution during polyslip in f.c.c. metals in investigated by the examples of Al, Ni, NiCo alloys and an AlMg alloy, deformed at room temperature either by rolling or by torsion. The principles governing this evolution appea

The shear strength of materials after extensive plastic flow under a superimposed high hydrostatic stress component is most conveniently studied by means of Bridgman opposed anvils between which thin disk-shaped samples are sheared through relative r

The microstructure observed in a Cu-Ni alloy fatigued in multiple glide consists of two sets of similar dipolar walls parallel to two different {100} planes. These are spaced approximately 0.5 μm apart within each set but are arranged in a non-rando

Several workers have observed growth spirals of very large step heights on platelet crystals, sometimes associated with polytypism. These are attributed to spiral growth round a sequence of similar screw dislocations in a close planar array or a sing

Ten roughly cubical armatures made of three different alloys in two different, albeit similar, designs were tested in an 1.5-cm-bore, 1-m-long EML (electromagnetic launcher), partly with lexan payloads. In payload tests, an arc penetrated between arm
