Utilization of Vacuum Technology in the Processing of Refractory Metal, Titanium and Their Alloys for Powder Applications

摘要

Increased usage of refractory metals, titanium and their alloys in the aerospace and electronics industries has led to the use of the hydride/dehydride (HDH) heat-treating process for recovery of spent materials. The HDH process has beers known for many years in the manufacturing of transition-metal powders. Gaseous hydrogehation of spent parts containing tantalum, niobium, vanadium or titanium provides a process in which unwanted end-use material can be converted to a crushed aggregate - including fine powder - and later degassed to provide clean material for new applications.
