Influence of intermetallic inclusions on the endurance of aluminum alloys

  • Published:
Materials Science Aims and scope

The results of experimental and theoretical investigations of the influence of intermetallic inclusions on the fatigue limit of secondary aluminum alloys are presented. We study AK8M3 secondary silumin. The influence of the content of iron in the alloy on the fatigue limit and intermetallic inclusions is analyzed. It is shown that the size and volume fraction of inclusions increase and the fatigue limit decreases as the content of iron increases. It is experimentally demonstrated that the treatment of alloy with a special modifying complex [2] leads to the globularization of intermetallic inclusions and increases the fatigue limit. We propose analytic dependences for the determination of the influence of intermetallic phases on the fatigue limit of heterogeneous aluminum alloys. By comparing the experimental and numerical values of the fatigue limit of AK8M3 alloy, we reveal their satisfactory agreement.
