Most sheet-metal fabrication of columbium and tantalum is done in the thickness range of 0.004 to 0.060 in. Columbium, like tantalum, can be welded to itself and to certain other metals by ...

The technique was originally developed for titanium alloys and materials requiring high processing temperatures. Pre-heating reduces deformation and inherent stress. To create 3D-printed parts from ...

The simulations will also help them develop recipes for tungsten alloys that can withstand the extreme conditions inside a nuclear reactor. “We’ll start with pure tungsten,” he said. “Eventually we’ll ...
