Characterization of deformed and undeformed Al-alloys

The experiment is aimed to characterize the nature of the material damage in a mechanically loaded specimen of a ductile aluminium alloy in order to get the input needed for damage mechanics based evaluation of structural components. In the first step the as-received and the homo¬geneously deformed conditions of the aluminium alloy shall be investigated by SANS. The objective is to identify and separate the main features responsible for the measured scattering effects and especially to find out the nature of the additional defects introduced by the mechanical loading procedure.
