Arc-Cast Tungsten Sheet Plate and Bar
The production of tungsten base alloys has advanced rapidly in the past few years. In a comparison of powder metallurgy and arc-cast products, the potential as well as the observed benefits by the arc-cast process must be analyzed since neither of the two products is considered optimum. The purification and homogenization which occurs during melting should provide improved ductility and reliability in the end-products. In the preliminary work on W-25Re, it has been shown that alloying can greatly improve the ductile-brittle transition temperature (DBTT), particularly when the alloy is arc-melted.
