Aerospace engineering articles from across Nature Portfolio

An article in Nature reports an alloy that can be 3D printed and has improved mechanical properties at high temperatures compared with current state-of-the-art 3D-printable alloys.

Additive manufacturing imparts defects in as-built titanium alloy microstructures, which form internally twinned nanoprecipitates with heat treatment to yield attractive mechanical properties.

Conflicting methodologies for estimating the CO₂ intensity of the space sector are beginning to emerge because of a lack of publicly available data, resulting in extensive variations that undermine the credibility of reported results.
