Low-cost titanium alloys? Iron may hold the answers

Spanish researchers have been looking at means of using alloying elements such as iron and chromium to make low-cost titanium alloys. They are not commonly used in conventional titanium processing, but PM techniques can avoid such problems as segregation and provide a way to develop new beta or alpha-beta alloys. They describe work on blending titanium powder with different iron-based powders to obtain alpha-beta alloys…
