CLA – Hitchiner process

...systems, these include: aluminium-based alloys nickel-based alloys stainless steels cobalt-based alloy for surgical implants. The CLV process is used for vacuum cast alloys, to reduce contamination by reactive elements such as nickel-, cobalt- and titanium-based alloys. Design: Gates (6–12 mm in length) are removed at a rate of 600 per hour to an accuracy of ±0.012 mm....

Hot isostatic pressing (HIP)

...systems will make process economical for a wider range of components. Pressures vary from 50 to 200 MPa, and temperatures up to 2000˚C with control to ±15˚C possible. Temperature depends on material, but should be high enough to cause diffusion-bonding and low enough to avoid any undesirable structural changes. Typical examples are Ti-6Al-4V, 900˚C; Al-7.5Si-0.5Mg,...

...system. Depending on the size of the chamber, several bags can be loaded into the space available. This is a batch process and compaction cycle time varies between 2 and 5 min. Dry-bag technique. Flexible bag is “fixed” in the pressure vessel and powder is loaded into the bag(s) without the bag having to leave the pressure vessel. The dry-bag technique lends itself to...

...systems. Converging (convex) lenses and converging (concave) mirrors each cause parallel rays of light to come together at the focal point, or focus, of the lens or mirror as shown below. In contrast, diverging (concave) lenses and diverging (convex) mirrors each cause parallel rays of light to spread out as if emanating from the focal point situated at a distance of one...
