摘要: Abstract The mechanisms that may lead to plastic instabilities are reviewed briefly, and their intimate connection with localization of shear is emphasized. combination macro micro experiments, ie, analysis stress fluctuations serrations, slip band evolution during deformation, for investigations these demonstrated examples LUDERS PORTEVIN-LeCHATELIER propagation in single glide oriented crystals, formation predeformed mono- polycrystals as well amorphous materials. problems connected collective effects the units deformation (ie, dislocations crystalline, local transformations materials) indicated, necessity study mechanism transfer (shear) neighbouring regions stressed.
