Oxide dispersion strengthened 304L stainless steel produced by ink jetting and laser powder bed fusion

Creator:

Paul, Brian K., Lee, Kijoon, He, Yujuan, Ghayoor, Milad, Chang, Chih-hung, and Pasebani, Somayeh

Abstract:

This paper discusses the fundamentals of a novel hybrid method to synthesize oxide dispersion strengthened (ODS) 304 L stainless steel (SS) alloy using a modified laser powder bed fusion (LPBF) machine. Previously, ODS metal matrix composites have been produced by LPBF via ball-milling, which is expensive to scale. Here, we selectively...

Selective laser melting of austenitic oxide dispersion strengthened steel: Processing, microstructural evolution and strengthening mechanisms

Creator:

Ghayoor, Milad, Lee, Kijoon, He, Yujuan, Chang, Chih-hung, Paul, Brian K., and Pasebani, Somayeh

Abstract:

Oxide dispersion strengthened (ODS) alloys exhibit superior mechanical properties due to the presence of nano-sized thermally stable oxide particles. However, manufacturing of ODS alloys is very complex and composed of numerous time consuming steps such as mechanical alloying, which is one of the main barriers toward the widespread application of...

Selective laser melting of 304L stainless steel: Role of volumetric energy density on the microstructure, texture and mechanical properties

Creator:

Ghayoor, Milad, Lee, Kijoon, He, Yujuan, Chang, Chih-hung, Paul, Brian K., and Pasebani, Somayeh

Abstract:

The role of volumetric energy density on the microstructural evolution, texture and mechanical properties of 304L stainless steel parts additively manufactured via selective laser melting process is investigated. 304L is chosen because it is a potential candidate to be used as a matrix in a metal matrix composite with nanoparticles...
