Applying their Materials by Design methodologies, QuesTek Innovations has expanded their ICME framework under US Army Small Business Innovation Research (SBIR) funding to adapt their high-performance Ferrium C64 gear steel to AM processes to demonstrate printability across multiple systems, achieve AMS minimum tensile properties, and observe a positive response to heat treatment.
Writing about additive manufacturing (AM) and the 3-D printing of gears is somewhat akin to publishing an updated dictionary. A new edition dictionary is literally already out of date before it hits Amazon's
or your local bookseller's shelves. New words are coined and definitions are updated constantly. So it is with AM: The technology is evolving so quickly that technical papers and other sources of AM information require constant revision.
QuesTek Innovations LLC is applying its Materials by Design computational design technology to develop a new
class of high-strength, secondary hardening gear steels that are optimized for high-temperature, low-pressure (i.e., vacuum) carburization. The new alloys offer three different levels of case hardness (with the ability to “dial-in” hardness profiles, including exceptionally high case hardness), and their high core strength, toughness and other properties offer the potential to reduce drivetrain weight or increase power density relative to incumbent alloys such as AISI 9310 or Pyrowear Alloy 53.
