ADVANCES IN TITANIUM METAL INJECTION MOLDING

摘要

The approaches to production of titanium powder injection molded parts are reviewed. Historically, oxygen levels have been too high for structural use (particularly with the Ti-6A1-4V alloy). However, recent advances in starting powders, binders and sintering facilities now allow oxygen levels in the Ti-6A14V alloy to be controlled to about 0.2 wt. % oxygen. This should result in significant expansion of the titanium PIM market place into aerospace, automobiles, surgical instruments, dentistry, communication devices (such as computers and cell phones), knives and guns.
