With this background of knowledge the man who contemplates a crystal aggregate and tries to understand how it behaves when forced to flow, is in much the same position as

Jürgen Boelcke,Bernard Straub,Paul ThieleThe exceptions (“whiskers”) prove the rule. The behaviour of dislocations is now understood in considerable detail, but their origin is still understood very imperfectly. We know of the ways, in which deformation can multiply the dislocation content of a crystal. We can also see that the recovery pr

Experimental measurements are in broadly satisfactory agreement with this theory for many metals, although reproducible discrepancies are observed which are thought to be due to the influence of the rate of strain in modifying the stress-strain relation .

Lorsque pendant la déformation plastique, on observe des lignes de glissement, celles-ci forment plusieurs faisceaux, de directions différentes, qui apparaissent à la surface de chaque grain, dès le début de la déformation. Certains faisceaux s’arrê
