Dislocation ordering and texture strengthening of naturally aged Al-Cu-Mg alloy
文献摘要：
Stability of grain structure,dislocation ordering and strengthening mechanisms of the naturally aged Al-Cu-Mg alloy after solution treatment are investigated by using optical microscope(OM),scanning electron microscope(SEM),electron back-scattered diffraction(EBSD),X-ray diffraction(XRD)and transmission electron microscope(TEM).Results show that{100}＜001＞,{100}＜110＞,{110}＜110＞and{110}＜001＞slip systems can be activated after solution treatment,which can promote the formation of{110}＜001＞Goss texture.The combination effect of T-Al20Cu2Mn3 phase and Goss-oriented grains with large Taylor factor makes the solution-treated alloys display excellent stability of grain structure.The enhanced yield strength of the alloy is ascribed to grain-refine strengthening,dispersed particles strengthening,dislo-cation strengthening and texture strengthening.The coarsening of the second phase is responsible for softening of the alloy after annealing at 400℃+solution treatment at 475℃.
