QuesTek is recognized as a global leader in materials science and engineering, and focuses on having a metallurgical understating of materials processing and performance issues.
There are significant materials challenges in metallic Additive Manufacturing, and QuesTek has been at the forefront of research in modifying the alloy chemistry (to improve mechanical performance and ensure printability) and optimizing heat treatment processes of the major alloy systems including high strength steel, stainless steel, aluminum, nickel, titanium, copper, magnesium and refractory alloys.
In addition, QuesTek has designed, atomized, printed and measured properties on several new alloys that have performance improvements over current legacy alloys commonly used today in AM. These materials are available as powder and/or wire for AM trials and application:
- High strength, carburizable Ferrium C64 steel for gears, tools and dies
- Higher strength and ductility upgrade over Ti-6-4
- Printable aluminum alloys with (i) high strength at room temperature (82 ksi YS and 8% el) and (ii) at high temperature (35 ksi YS at 250°C)
