A.H. Cottrell led a large team of scientists and engineers as Deputy Director of the Metallurgy Division of the Atomic Energy Research Establishment at Harwell, between 1955 and 1958. The team sought to develop a fundamental understanding of the effe

Publisher Summary This chapter presents a brief overview of work hardening. The turbulent flow of fluids is the most difficult remaining problem in classical physics. Work hardening is worse. The great complicating feature of fluid flow—the presenc

An analysis is made of published data on the recovery of resistivity during the annealing of metals at low temperatures, after damage by irradiation, quenching, or cold work. Interpreted in terms of the migration and annihilation of point defects, th

Crystals of ordered beta brass slip along 〈111〉; those of ammonium and thallium halides slip along 〈100〉. These observations can be interpreted in terms of partial dislocations in the simple cubic lattice of the caesium chloride structure. Wh

Summary A large increase in the critical shear stress of high-purity aluminium single crystals can be achieved by water quenching, instead of furnace cooling, after annealing at a high temperature. This quench-hardening effect is insensitive to purit

Substitutional solute atoms in aluminium usually diffuse too slowly to cause appreciable strain ageing at room temperature. However, if the concentration of vacancies is increased by plastic deform...

N otch bend tests have been made on 3 % Si steel at 295°K and 77°K, and compared with plain tensile tests on the same material. A sensitive etching technique has been used to detect the earliest stages of plastic yielding from the observation of in

The effects of plastic twisting on the tensile deformation of aluminium crystals are examined. After such a twist the tensile stress needed to continue tensile straining is sharply increased and, in some cases, this is followed by a period of increas

When a single crystal of alpha-brass is strained in tension the conjugate slip system does not become fully active until the tensile axis has “overshot” the [100]–[111] symmetry line appreciably. Experiments on such crystals described in the pr
