Structure Investigations of Pattern Welded Swords
This link hub does not have many members as of now (July 2014). That is partially due to the fact that the results of metallurgical investigations of this kind are often published in obscure journals (and languages) and I simply may have overlooked some. However, I'm pretty sure that there aren't many papers out there as of now.
Here I give links to excerpts of papers that I found interesting.
     
Paper Keywords
Erik Szameit, Mathias Mehofer Detailed analysis of swords and saxes from Austria; 750 AD - 900 AD
