LOW-COST TITANIUM ALLOYS FOR TITANIUMPOLYMER LAYERED COMPOSITES

摘要

Two pilot low-cost near-alpha (Ti–Fe–Zr–O– N) and alpha+beta (Ti–Al–V–Fe) alloys have been developed specially for titanium-polymer layered composites, which allow a 30 percent weight reduction in comparison to that of Albased alloys. The new alloys are doped with REM and possess an increased contact corrosion resistance.
