Titanium alloys, widely used in the aerospace, automotive and energy sectors, require
complex casting and thermomechanical processing to achieve the high strengths required
for load-bearing applications. Here we reveal that additive manufacturing can exploit
thermal cycling and rapid solidification to create ultrastrong and thermally stable titanium
alloys, which may be directly implemented in service. As demonstrated in a commercial
titanium alloy, after simple post-heat treatment, adequate elongation and tensile strengths …
