GIVING LIFT TO AEROSPACE RECOVERY It’s been a yearlong, bumpy ride for the aerospace industry. But despite experiencing a pandemic-induced sharp descent, analysts forecast a recovery beginning this year (albeit quicker for the defense sector than commercial). And engineering will be key to that recovery. According to Deloitte, technological advancements and innovation could transform the industry and lead to long-term growth. Out on the horizon, areas of emerging technologies include advanced aerial mobility (AAM is being advanced by NASA and the Federal Aviation Administration), hypersonics (such as defense glide vehicles and cruise missiles), electric propulsion (e.g., Rolls-Royce’s hybrid version of the M250 gas turbine), and hydrogen-powered aircraft (e.g., a planned zero-emission aircraft from Airbus). While those innovations may sound too high in the clouds, in this issue we share some titanium advancements related to current aviation technology. First, “Titanium Microtexture 101”—Part I of a two-part series—explains this longstanding fatigue-related phenomenon in aerospace components. Second, we share how recent improvements to near net shape titanium extrusion make it a viable manufacturing option, not just for long structural components as it has been traditionally used, but for additional types of aircraft parts. Back on the ground, Patricia Silvana Carrizo—who prompted the formation of ASM’s Archaeometallurgy Community and has been leading its efforts—dug around in South America to bring us a review of copper artifacts found in her homeland of Argentina. Her study of these historic metals is fascinating as it traces their usage from before the 1500s through post-colonial times. Look for more archaeometallurgy articles later this year as outgrowths of this new ASM Connect community. In other copper news, we celebrate a recent announcement by the U.S. Environmental Protection Agency (EPA). Certain copper alloys have now been recognized by the EPA as having long-term efficacy against the virus that leads to COVID-19. In our Materials Science and Coronavirus series, Harold Michels shares his insights into what the announcement means for existing and future copper product registrations. In addition, the EPA statement provides further rationale for hospitals, extended care homes, and public transportation facilities to coat high-touch surfaces with copper alloys. We applaud the announcement! Likewise, the U.S Food and Drug Administration (FDA) recently released new guidance on the use of Nitinol in medical devices. We are honored to have authors from the FDA add context to the government document in their article in our SMST NewsWire supplement in this issue. And finally, circling back to aerospace, Mitchell Dorfman, FASM, TSS-HoF of Oerlikon Metco, will be viewed on computer screens around the globe as the joint keynote speaker at our co-located AeroMat and ITSC Virtual Events this May. Check out the show previews for both events included in this issue. Dorfman will describe how current challenges faced by the airlines and engine manufacturers—compounded by COVID-19—necessitate innovations in engine efficiency alongwith environmentally friendly advancements. He believes reliable and costeffective solutions will be required related to higher engine operating temperatures, new lighter weight components, andunique surface solutions for increased longevity of parts. As the aerospace industry makes its gradual ascent, technological innovations based on materials science will be more critical than ever. joanne.miller@asminternational.org
