Titanium is used regularly in aviation for its resistance to corrosion and heat, and its high strength-to-weight ratio. Titanium alloys are generally stronger than aluminium alloys, while being lighter than steel. It has been used in the earliest Apollo Program and Project Mercury. [36]
Osmium diboride (OsB 2) has a high bulk modulus of 395 GPa and therefore is considered as a candidate superhard material, but the maximum achieved Vickers hardness is 37 GPa, slightly below the 40 GPa limit of superhardness. A common way to synthesize OsB 2 is by a solid-state metathesis reaction containing a 2:3 mixture of OsCl 3:MgB 2. [10]
Studies of titanium alloys used in armors began in the 1950s at the Watertown Arsenal, which later became a part of the Army Research Laboratory. [ 2 ] [ 3 ] A 1948 graduate of MIT, Stanley Abkowitz (1927-2017) was a pioneer in the titanium industry and is credited for the invention of the Ti-6Al-4V during his time at the US Army’s Watertown ...

Titanium is a common material for backpacking cookware and eating utensils. Though more expensive than traditional steel or aluminium alternatives, titanium products can be significantly lighter without compromising strength. Titanium horseshoes are preferred to steel by farriers because they are lighter and more durable. [115]
Titanium aluminide (chemical formula TiAl), commonly gamma titanium, is an intermetallic chemical compound. It is lightweight and resistant to oxidation [ 1 ] and heat, but has low ductility . The density of γ-TiAl is about 4.0 g/cm 3 .
Like many other alloys, titanium gold alloys have a higher yield strength, tensile strength, hardness, and magnetism than either of its constituent metals. [ 4 ] In July 2016, researchers led by Emilia Morosan at Rice University discovered that a titanium-gold alloy, β-Ti 3 Au, is an intermetallic alloy that is up to 4 times harder than pure ...
