A novel ultra-high strength and low-cost as-cast titanium alloy

A novel ultra-high strength and low-cost as-cast titanium alloy

A novel low-cost titanium alloy (Ti-22Fe-4Si-4Cr) is reported, which has a very high compressive strength of 2.5GPa and ultra high hardness of 710Hv in as cast condition. The specific strength of the alloy is 488kN·m/kg, one of the highest among all engineering materials.
