With our diverse editorial coverage, there are a number of associations in our industry. I personally belong to APMI International (MPIF) for powder metals and additive manufacturing as well as AIST (Association for Iron & Steel Technology). That’s in addition to IHEA and MTI, of course.
At its halfway point, a project to industrialize additive manufacturing (IDAM) has resulted in a new metal powder, DP 600. GKN Powder Metallurgy, one of 12 project partners, says that its dual-phased steel is a good candidate for several structural automotive applications because the mechanical properties can be enhanced with heat treatment.
Ford pointed out a “complex extrusion” on the F-150 cab, which cannot be sectioned. The part contains internal reinforcement vanes that cannot be reattached after sectioning. Ford also warned against installing approved Ford rivets in arbitrary locations on the vehicle body.
Japanese scientists have developed a machine-learning approach that can predict the elements and manufacturing processes needed to obtain an aluminum alloy with specific, desired mechanical properties. The program learns about exiting materials, including alloying elements, mechanical processing and heat treatment.
Hyundai's Nexo SUV is the first fuel-cell vehicle certified for use on Australia's roads. A fleet of 20 of the cars has been leased by the Australian government and is expected to be deployed later this year. To power the car, Hyundai is helping to develop more refueling stations.
The Russian steel industry will re-evaluate government-financed demand as the number of the country's long-term goals and associated investment programs was cut in half and their deadlines moved back to 2030 from 2024. It is believed the cuts and extensions were COVID-related.
As the earlier story indicated, creating alloys for AM is an ongoing effort. Some of the recent results have been an aluminum alloy from Amaero International (HOT Al), which has entered the final stage of approval for patent protection. Hot Al can be hardened after 3D printing for better properties and higher-temperature applications.
Jaguar Land Rover (JLR) is planning to build more cars from recycled beverage cans, bottle tops and end-of-life vehicles. Engineers have been able to mix recycled aluminum with some primary aluminum to form a new and tested prototype alloy comparable to JLR’s existing grade and quality.
The additive-manufacturing (AM) process as a whole involves turning 3-D CAD files on computers into finished products layer by layer –although AM specifically relates to the construction part of that process. What happens after the printing phase has concluded also matters, however, in order to ensure that products are ready for use.
Most vacuum furnaces currently active in the heat-treating world incorporate some form of, or combination of, graphite-felt insulation, with either a foil or board internal facing in the furnace hot-zone construction. The graphite felt used in high-temperature furnaces is either PAN-based or Rayon-based.
