Study of fatigue fractures of Al-Mn alloy

Original language description

Aluminum alloys have become a standard application in automotive industry due to their strength to weight ratio and corrosion properties. Aluminum alloys based on Al-Mn (class 3XXX) that are applied as components in air conditioning modules in automotive as well as in construction and consumer industries are often submitted to vibrations which can eventually lead to fatigue cracks and in the end to complete failure of the components. The study of fatigue failures of cyclic loaded Al-Mn alloy was performed using fractographic analysis on scanning electron microscope JEOL JSM-649OLV. The loading was realized from 100,000 to 1,369,000 cycles at room temperature. The features of fatigue fracture surfaces were discussed comparing different tempers of the A3003 alloy, specifically in the temper 1/4 hard (H12) and full soft (O). The results for corresponding loading cycles were compared. Areas close to the crack initiation were characterized by radial marks corresponding to fatigue propagation. Fracture was propagated through the growing lines in form of fine striations with secondary cracks and microcracks between them. The striations were arranged to bands and corresponded to crack propagation at each loading cycle. For final fracture the typical quasi-cleavage morphology was observed.
