Newly developed ATI 425 Alloy sheet can be produced with superior gauge control and improved surface finish, offering aircraft design engineers new opportunities for improving the manufacturability and weight-saving potential of aerospace components.
Allegheny Technology Industries of Pittsburgh said the material can be hot or cold rolled and annealed to produce sheet with strength comparable to conventional pack-rolled titanium 6-4 sheet, but with improved formability due to higher room-temperature ductility
Potential aerospace applications include fasteners, erosion strips, tail rotor blades, fuselage body panels and spars, and engine pylon and nacelle fittings.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
