Get this from a library. Electron-beam welding of thorium-doped iridium alloy sheets. [S A David; C T Liu; J D Hudson; Oak Ridge National Laboratory.]. Iridium and its alloys have been considered to be difficult to fabricate due to their high melting temperatures, limited ductility, sensitivity to impurity content and particular chemical properties.

The variety of processing methods used for iridium and its alloys are reviewed, including purification, melting, forming, joining and powder metallurgy techniques. @article{osti_, title = {Nonvacuum electron beam welding enhances automotive manufacturing}, author = {Powers, D.E.}, abstractNote = {Electron beam welding (EBW) is a high-energy-density beam welding method generally recognized as a viable production joining process.

This method is able to produce higher welding speeds, lower heat inputs and greater depth-to.
