... diagram ( Fig. 6 ). If the weld metal is austenite with a little ferrite, then the weld metal itself will have appreciable ductility, and only the HAZ will be at risk for cold cracking. This possibility can be minimized by using high preheat temperatures (200 °C, or 390 °F minimum for type 410 base metal...

... intermetallic compounds, which in turn embrittle the welds. Tantalum can be welded to other reactive metals, with which it forms solid-solution alloys that are harder than tantalum but have usable ductility. Listed below are some typical tantalum alloys. These alloys are basically solid-solution strengthened...
