| Abstract Scope |
Vacuum arc remelting (VAR) and electro-slag remelting (ESR) processes are widely regarded as closely competitive processes for the production of clean metals, particularly steels and Ni alloys. A critical review of the detailed mechanisms involved in the melting process draws attention to the serious defects which can be present in VAR ingots, rendering the material unfit for safety critical applications. It is deeply regretted that this is a serious and hugely unwelcome conclusion. In contrast, ESR is found to be largely free from serious defects, and can be recommended as a reliable remelting process capable of producing reliable products. |
