Název v původním jazyce

Structure of ultrafine-grained aluminium alloys prepared by ECAP

Popis výsledku v původním jazyce

One of the methods used for preparation of materials with very fine structure is Equal-Channel Angular Pressing (ECAP) which is based on the severe plastic deformation. The material is pressed through a die and deformed by shear at the intersection of two internal channels of the same cross section. Aluminium alloys processed by this technique may reach the grain size of hundreds of nanometers. Compared to their coarse grained equivalents these materials exhibit enhanced properties e.g. yield strength,ultimate tensile strength or elongation to failure. The aim of this work was to describe structural development of alloys based on Al-Mg-Sc during the ECAP processing and following uniaxial tensile testing at various temperatures and strain rates. The attention was paid especially to the grain size and their orientation during heat treatment and/or plastic deformation, size and distribution of intermediary phases and also crystallography. The transmission electron microscopy was used. Th
