Powder Injection Molding of Niobium

Materials Science Forum, 2005
Niobium and niobium-based alloys are used in a variety of high temperature applications ranging from light bulbs to rocket engines. Niobium has excellent formability and the lowest specific weight among refractory metals (Nb, Ta, Mo, W, and Re). Powder injection molding of niobium powder was investigated for efficiency of the process.

Powder injection molding of pure titanium

Rare Metals, 2009
An improved wax-based binder was developed for powder injection molding of pure titanium. A critical powder loading of 69 vol.% and a pseudo-plastic flow behavior were obtained by the feedstock based on the binder. The injection molding, debinding, and sintering process were studied.

Powder Injection Molding of Ti6Al4V Alloy

Materials Science Forum, 2007
An improved wax-based binder was developed for powder injection molding of Ti6A14V alloy. The molding behavior, debinding kinetics and sintering process were studied. Components with relative density of 96.5% were produced with PIM process. The density of the components was increased up to 99% by HIP treatment.
