Study of fracture structure of cylindrical samples of 6101 aluminum alloy under static tension after standard heat treatment

Abstract

In this work, the fracture structure of the material after static stretching to failure at room temperature is studied. To improve the group of elastic-plastic properties of metallic materials, thermal hardening and aging methods are used, which is associated with a change in the structure, physicomechanical properties and phase composition. In earlier works, the phase composition of the Al-6101 alloy was shown. This study is supplemented by a new result: inclusions of Fe-based particles along the boundaries of the fracture pits were considered. Their overwhelming majority in comparison to other inclusions was shown, which allowed us to draw a conclusion about their influence on the overall process of destruction as one of the factors influencing direct destruction.
