Creep in Al single crystal processed by equal-channel angular pressing

Popis výsledku v původním jazyce

In this work the creep behavior and microstructure changes in aluminum single crystal during equal-channel angular pressing (ECAP) were investigated in order to understand the relationships between microstructure and creep behavior. The investigated crystal was oriented with {111} parallel to the shear plane and <110> was parallel to the direction of shear. During ECAP by route A at room temperature single-crystalline sample was subsequently transformed into the polycrystalline material. Microstructuresof single crystals processed by 1 and 4 ECAP passes were characterized by transmission electron microscope (TEM) and scanning electron microscope (SEM) equipped with the electron backscatter diffraction unit (EBSD). Microstructure analyses showed inhomogeneity of microstructure after ECAP and the increase in the fraction of HAGB?s (>15°) with increasing number of ECAP passes. Tensile creep tests at temperature of 373 K and at applied stress of 50 MPa were performed on the Al single crys
