Von der Schule in die Arbeitsweltrecovery due to dislocation rearrangement and pair annihilation proceeds quickly. Sometimes recrystallization occurs during deformation. For polycrystalline metals, grain boundary sliding and migration also play an important role. Under a very low stress, the deformation occurs not by dislocation moPRE 发表于 2025-3-27 03:05:46
Von der Schule in die Arbeitswelton motion at high temperatures, jogs in screw dislocations and interdislocation interaction are considered in pure metals, and in addition, the interaction between dislocations and solute atoms in alloys. The resistance of these obstacles of course exists also at low temperatures. However, the effecGuileless 发表于 2025-3-27 09:13:59
Von der Schule in die Arbeitswelt ductile but low in strength. Many efforts are being made to produce composite materials having both high strength and ductility by combining them. Even in composite materials the strength decreases at high temperatures in many cases. The decrease is also caused by the increase in diffusion velocitychronology 发表于 2025-3-27 11:05:05

Dislocations and Their Fundamental Properties, demonstrated. Thus, the year 1934 is generally recognized as the birth-year of the dislocation. During the following few years, the elasticity theory of dislocations was established. Since the 1950s, various new experimental techniques, such as electron microscopy, have been developed and have contoutrage 发表于 2025-3-27 18:20:45

Dislocation Motion in the Field of a Random Distribution of Point Obstacles: Solution Hardening,various barriers. So far, the problems have been discussed using the following implicit solutions: (1) the processes are quasi-static and do not involve any dynamical aspects; (2) the frictional forces produced in materials are neither extremely large nor small. If the frictional forces due to the m解冻 发表于 2025-3-28 06:05:29

Dislocation Motion Controlled by the Peierls Mechanism,f the dislocation changes with the periodicity of the lattice. This periodic potential energy with respect to the dislocation position is called the ., after the researcher who first estimated this potential theoretically for a simple model .
