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 ...

Evaluation of single tracks of 17-4PH steel manufactured at different power densities and scanning speeds by selective laser melting

South African Journal of Industrial Engineering, 2016
In Selective Laser Melting, the initial units produced are single tracks that overlap to create a single layer; from the sequence of layers, a 3D object is manufactured. The properties of the parts produced by SLM depend heavily on the properties of each

Effect of microalloying with titanium on the properties of 17-4PH martensitic stainless steel

Journal of Engineering Sciences and Innovation
The 17-4PH (UNS S17400, 630) alloy is a martensitic stainless steel from the chromium-nickel-copper alloying system with the addition of niobium, in-situ strengthened by precipitation of intermetallic compounds. It is distinguished by superior mechanical properties and high corrosion resistance, being frequently used in applications requiring special ...
