Fabrication of Fe-Cr-Al oxide dispersion strengthened PM2000 alloy using selective laser melting

Significance of output:

This paper was the first to show that melt-sensitive oxide dispersion strengthened powder metallurgy alloys such as Fe-Cr-Al PM2000 alloy could be successfully processed into solid components using Selective Laser Melting (SLM). High solidification rates prevented coarsening of dispersion strengthened particle diameters, which usually occurs during melting and compromises the high temperature creep strength of these alloys. The work has been internationally cited, attracted attention from Siemens (Gordon McColvin) as a surface manufacturing process and was the foundation for further work that aimed to produce novel heat exchangers for space applications.
