Texture Gradient Effects on the Mechanical Response of a Rolled Tantalum Plate (.pdf)
OIM measurements were used to understand the unusual mechanical behavior observed in tantalum plate. The material used in this study was rolled and annealed vacuum arc-re-melted tantalum plate. Cylindrical compression specimens were machined from the plate in the orientations shown in figure 1

their radiation can be turned on and off. To generate X-rays, the electron accelerator needs to be equipped with an X-ray converter. The X-ray converter is designed to stop the accelerated electrons and is typically a water cooled tungsten or tantalum plate in an appropriate mechanical assembly. A lot

Refractory Metals
, tantalum, molybdenum, and columbium (niobium). They are mutually soluble and form solid-solution alloys with each other in any proportion. These four refractory metals and their alloys are available in mill forms as well as products such as screws, bolts, studs, and tubing. Although the melting points

is known as the beta-transus temperature. Alloying additions such as chromium, columbium, copper, iron, manganese, molybdenum, tantalum, and vanadium stabilize the beta phase by lowering the temperature of transformation from alpha to beta. Some elements, notably tin and zirconium, behave as neutral
