Review on Fatigue of Additive Manufactured Metallic Alloys: Microstructure, Performance, Enhancement, and Assessment Methods

Advanced Materials, Volume 36, Issue 17, April 25, 2024.
Additive manufactured metals have excellent mechanical properties, but their fatigue resistance is an exception. This article reviews the processes attributes, hierarchical microstructure, fatigue performance, and evaluation methods. The fatigue failure mechanisms of printed metals were summarized, and the competition between trans‐scale ...

Integrity Assessment of Electron‐Beam‐Welded Joints of Additively Manufactured AlSi10Mg Components

Advanced Engineering Materials, Volume 26, Issue 2, January 2024.
Electron beam welding is employed to join AlSi10Mg specimens fabricated via powder bed fusion‐laser beam (PBF‐LB/M) and casting. The study explores the quasistatic and fatigue behavior of similar and dissimilar welded joints in different combinations, alongside thorough microstructure analysis, to assess the correlation between the microscopic and ...

Effect of shot peening on fatigue behavior and microstructure of additively manufactured Co‐Cr‐Mo alloy

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 1, Page 240-253, January 2024.
Abstract This investigation delved into the impact of shot peening on the fatigue properties of Co‐Cr‐Mo samples manufactured through laser powder bed fusion. Two primary groups were established, one subjected to stress relief heat treatment. Each group underwent further division, with one subgroup undergoing shot peening. Comprehensive microstructural,
