Near-Net-Shape (NNS) technology for advanced engineered materials provides a number of supply chain benefits.
These benefits include less input material, less machining hours and overall greater through put in comparison to
conventional rectangular and round machining stock. Al-62%Be alloy has a unique combination of properties attractive
for optical structures. It has a density of 0.076-lb/in3, 28-ksi minimum yield strength and 28-Msi elastic modulus.
There have been significant developments with AlBe Hot Isostatic Press (HIP) consolidation technology in recent years.
One key is using spherical AlBe metal powder which packs to a high density. The high packing density allows more
complex can design and dimensional control to produce monolithic parts with isotropic properties. Other key success
factors are HIP can design and the process to implement the near-net-shape strategy.
This paper will describe an example of a process using shaped HIP cans to produce blanks approaching near-net-shape
design through an iterative process. The strategy is to produce a seamless product to the next step in the supply chain as
the iterations improve material utilization efficiency. The economic impact and planned future work will also be
