First principles computation of composition dependent elastic constants of omega in titanium alloys: implications on mechanical behavior (open access)

First principles computation of composition dependent elastic constants of omega in titanium alloys: implications on mechanical behavior

Article on the poor mechanical properties of Ti alloys. The study shows that the elastic properties of the ω-phase can be systematically varied as a function of its composition to enhance both the ductility and strength of the Ti-alloy. Furthermore, that ω precipitates are not intrinsically embrittling and detrimental and that Ti-alloys can be created with both good ductility and strength by tailoring ω precipitates' composition instead of completely eliminating them.
