A utomotive materials are at the heart of our spring is- sue, with a timely update on thixoforming and some highlights from Jaguar, Honda, Audi, and Ford’s jour- ney into the automotive aluminum space. Looking back at last year’s May/June issue, we had just published the first his- torical article on this topic. The series was originally planned as five parts: We now find ourselves in May 2019, with Part VII of what has grown into a spirited 10-part series. As I write this column, I’m in the midst of ASM’s 30th annual aerospace conference—AeroMat—and enjoying both the nitty-gritty technical sessions and the high-level keynote talks. One session I attended covered evaluation of hot isostatic pressing (HIP) parameter effects on additively manufactured (AM) Ti-6Al-4V and featured four speakers, from Finland, Australia, Ukraine, and the U.S. One curious point was that the ASTM standard currently followed for HIP of titanium AM parts was actually developed around 30 years ago for cast titanium. The gist of the HIP standard is that it calls for 900°C at 100 MPa for two hours. The speakers had all run different experiments tweaking the temperatures at various intervals down to 800°C, adjusting the pressure levels and time, and also checking out some rapid quench cycles. The consensus seemed to be that more experiments are needed, and the ASTM standard may require some revision to better suit AM titanium parts. The keynote sessions took a higher level view and were equally fascinating. Marilyn Gaska of Lockheed Martin talked about U.S. national defense strategy and what it means to be agile these days. Some of the main building blocks in- clude a strong digital twin environment, advanced materials (such as ultra-high temperature and adaptive/self-healing capabilities), and agile manufacturing processes such as onsite AM for replacement parts. Gaska stressed that the time- frame of “when I need it to when I get it” must be drastically reduced, which is now a prioritized work in progress. Atherton Carty of Lockheed Martin Skunk Works gave a riveting historical overview of his program area, beginning in 1943 and continuing through today. The division’s main goals are to develop special mission aircraft, win and pro- totype new programs, develop and leverage game-changing technologies, and create improvements and derivatives of current systems. Carty discussed several iconic aircraft in his talk, including the XP-80, U-2 Angel, SR-71 Blackbird, F-117A stealth fighter, F-22 Raptor, X-35, Polecat, X-55, LBFD X-plane, and the LMH-1 hybrid airship designed for affordable remote cargo operations. Each aircraft included a steep learning curve and was accomplished on a tight timeline, and Carty’s lecture served as a respectful tribute to the engineers who spend their careers moving aerospace technology forward. Next up was Rich Rainen, chief mechanical engineer on the Mars 2020 proj- ect for the NASA Jet Propulsion Laboratory (JPL). The main objectives of Mars 2020 are to determine what life may have existed on Mars, characterize the plan- et’s climate and geology, and prepare for human exploration. Beyond the incred- ible feat of landing a rover safely on the surface, Rainen talked about some other lofty goals for Mars 2020—collecting rock samples for return to earth at a later date, and launching a Mars helicopter to fly around and take pictures. Hats off to the creative engineers at JPL who are pushing the boundaries of both space exploration and materials engineering. frances.richards@asminternational.org MATERIALS INNOVATIONS FOR EARTH AND SKY
