Titanium and ITS Alloys

Titanium was first identified as a constituent of the earth's crust in the late 170Os. In 1790, William Gregor, an English clergyman and mineralogist, discovered a black magnetic sand (ilmenite), which he called menaccanite after his local parish. In 1795, a German chemist found that a Hungarian mineral, rutile, was the oxide of a new element he called titan, after the mythical Titans of ancient Greece.
