Casting of metals ranges from sand casting to investment casting that are used to create near net shape metal parts by pouring molten metal into a pattern.
Casting Processes in the Aerospace Industry
Metal casting includes a range of different techniques and alloy classes for making aerospace parts.
Gas turbine engines are constructed of the most advanced titanium alloys, nickel and cobalt superalloys. For example, most jet engine turbine blades today are made of single-crystal alloys, which have greater strength and can operate at higher temperatures than conventional alloys. These blades have sophisticated air cooling channels are made by investment casting. More information can be found here.
NSL is supporting the aerospace casting industry with chemistry testing of witness samples to confirm their specification and providing failure analysis services when for example microstructure challenges arise during the production process. We also provide mechanical testing at both ambient temperature and stress rupture, creep, and elevated temperature tensile testing.
