THE EFFECT OF NANOSCALE DEFECTS ON THE DYNAMIC YIELD STRESS OF ALLOYS
The high strain rate deformation of aged alloys containing Guinier-Preston zones is theoretically analyzed. The analytical expression for the contribution of the Guinier–Preston zones to the value of the dynamic yield stress has been obtained. It is shown that the dynamic drag of dislocations by nan...

| description |
The high strain rate deformation of aged alloys containing Guinier-Preston zones is theoretically analyzed. The analytical expression for the contribution of the Guinier–Preston zones to the value of the dynamic yield stress has been obtained. It is shown that the dynamic drag of dislocations by nanoscale defects differs significantly from the drag by point defects. |
