Very high cycle fatigue (VHCF) response of additively manufactured materials: A review

Abstract

Recently, the diffusion of components produced through additive manufacturing (AM) processes has significantly increased. Concurrently, to ensure the safe employment of AM components, the research has focused on the assessment of their fatigue response. In the present paper, a comprehensive literature review on the very high cycle fatigue (VHCF) response of materials produced through AM processes is provided. The experimental results on the VHCF response of Ti6Al4V, AlSi10Mg, AlSi7Mg, AlSi12, IN718, and 316L specimens produced through different AM processes are summarized. The main factors affecting the VHCF response of AM materials are finally compared and critically analyzed.
