The full potential of additive manufacturing (AM) has been limited by the process induced defects within the fabricated materials. Defects such as lack of fusions and gas entrapped pores act as stress concentrators and ...

Additively manufactured components are intended for use in load bearing applications, which are often accompanied by fluctuating external loadings. Therefore, understanding the fatigue behavior of AM materials under ...

This study aims to understand the effect of build platform preheating on the microstructural features and mechanical properties of 316L stainless steel (SS) fabricated via laser beam powder bed fusion (LB-PBF) process. ...

Nickle based super alloys such as Inconel 718 are being extensively used to manufacture turbine blades for jet engines due to their superior mechanical properties at higher working temperatures. Furthermore, poor ...

Additive manufactured (AM) materials are prone to internal defects such as entrapped gas pores and lack of fusions along with having a rough surface. There are different types of fatigue tests that are used to characterize ...

Laser surface treatment of additively manufactured parts has attracted considerable interest in the past few years due to its flexibility, operation speed, and capability for polishing complex surfaces as compared to ...

This study utilized a defect sensitive fatigue model based on a fracture mechanics concept to predict the fatigue life of 17-4 precipitation hardening (PH) stainless steel (SS) fabricated using laser beam powder bed ...

The fatigue behavior of additive manufactured parts in the as-built surface condition is typically dominated by the surface roughness. However, the fatigue behavior of 304L stainless steel fabricated by laser beam powder ...

Additive manufacturing (AM) is becoming a more viable manufacturing process in the biomedical, aerospace, nuclear, and defense sectors as a means to fabricate near net shaped parts on demand. Austenitic stainless steels ...

In this study, the very high cycle fatigue (VHCF) behavior of Inconel 718 manufactured via a Laser Beam-Powder Bed Fusion (LB-PBF) process is investigated. LB-PBF Inconel 718 specimens are fabricated in vertical direction ...
