Sintering Finished Productsor pre-form for post-processing
Hydrogenation followed by simultaneous de-hydrogenation & sintering are twoinnovative aspects of our invented process that are the key in reducing the cycletime to <24 hours (i.e., 5-fold reduction) leading to ~50% energy savings and costreduction of ~20%.

“…passed with flying colors, met the forging specification requirements, as wellas the plate specification requirements (MIL‐DTL‐46077)… this is the best result we have seen from any PM based, no melt, low cost material” (BAE 7‐6‐2010 test report)

The powder-based rolled mill Ti-6Al-4V productsform static tensile, fatigue, and fracture propertiesthat match similarly-processed ingot-based Ti-6Al-4Vhot-rolled products
The blended elemental hot-rolled P/M Ti-6Al-4V alloymill products met the AMS Specification mechanicalproperty requirements for both static loading, as wellas damage tolerant fracture toughness and cyclicS/N fatigue endurance limit for aerospaceapplications.

CONCLUSIONSInnovative powder metallurgy processes for manufacturing the titaniumcomponents for critical applications from hydrogenated titanium powder thatincludes various room temperature consolidation techniques (die-pressing, directpowder rolling, and cold iso-static pressing) followed by sintering and hightemperature post processing (forging, rolling, extrusion, ring rolling weredeveloped.
The low cost ADMA patented blended elemental powder metallurgy processes(ADMATALTM) provide the best combination of mechanical properties that meet orexceed the properties obtained on the identical titanium alloys by conventionalingot metallurgy processes.
