ResumoAn interesting new development in nonferrous metallurgy seems to be taking the world by storm. The topic is scandium, a rare metal that is now being mined in the Ukraine. Known for its toughness, it was formerly a top secret material used in fighter planes, including the MIG 29, during the existence of the Soviet Union. This metal is now being introduced into a variety of aluminum alloys in this country, both in base metal and filler metal forms. The results are increases in strength, fatigue life and weldability. US interest in scandium-containing products is burgeoning, examples include aircraft, components for automobiles and trucks, high-speed trains, and boats. The technology is being developed and implemented at two laboratories, one in Baltimore, MD, and the other in Kiev, Ukraine. Both laboratories belong to Ashurst Technology Ltd., Hamilton, Bermuda. The author recently visited the Baltimore laboratory where he learned more about scandium and its current and potential effects on industry. This report documents what he learned.
