| Abstract Scope |
Spin forming is a thermo-mechanical deformation process for manufacturing axi-symmetric geometries by incrementally shaping a metal blank to a mandrel. While this technique originated in the 10th century, starting in the 1950s it was investigated as a potential route to form refractory alloys, which are notoriously difficult to thermo-mechanically process. Spin forming relies on localized deformation initiated by one or more moving rollers, where the degree and intensity of this localization are a function of process parameters and affect the macroscopic forming response. Here, we present an overview of the spin forming technique, it’s history with refractory alloys, and recent microstructure evolution results from spin-forming a Ta-2.5wt%W alloy. |
