 ZrO2 Nanoparticles in Fe20Cr Oxide Dispersion-Strengthened Alloys Processed by Laser Powder Bed Fusion

The study investigates oxide nanoparticles (ONPs), specifically ZrO2 nanoparticles in Fe20Cr alloys, produced via laser powder bed fusion (PBF-LB/M), in order to understand how these nanoparticles impact the microstructure and mechanical properties. LiteScope was used for validating Electron Channeling Contrast Imaging (ECCI) findings and to distinguish nanoparticles (ONPs) from pores or preparation artifacts.

We’re happy to see LiteScope AFM-in-SEM contribute to this important study, particularly in supporting Marina Macias Barrientos and her team in validating Electron Channeling Contrast Imaging (ECCI) findings.


The study explores the integration of ZrO2 nanoparticles into Fe20Cr alloys processed by Laser Powder Bed Fusion (PBF-LB/M). The team investigated how different synthesis methods, including laser-generated and chemically synthesized nanoparticles, impacted dispersion, agglomeration, and creep resistance. LiteScope helped validate ECCI findings, distinguishing nanoparticles (ONPs) from pores or preparation artifacts and contributing to the nanoscale characterization of the material.


This research provides valuable insights into how nanoparticle concentration and dispersion can influence the mechanical properties of oxide dispersion-strengthened (ODS) steels, offering guidance for the development of advanced materials in additive manufacturing.
