Vacuum-die casting titanium for aerospace and commercial components

Vacuum-die easting offers a high-quality, low-cost alternative for manufact uring titanium components. Lower costs are obtained through the elimination of processing steps that are associated with other manufacturing methods, such as investment casting. However, vacuum-die-cast component geometry is limited to single-plane, solid components weighing less than 18 kg. Initial mechanical property tests performed on vacuum-die-cast Ti-6Al-4V show prop erties similar to that of wrought material, which could lend to the direct substitution of vacuum-die casting components for wrought components. Addit ionally, the quality of vacuum-die-cast components shows improvement over i nvestment castings through the elimination of alpha-case and the use of cer amic-less casting system.
