Fe-Al
|ef-ee-ay-el|
/ɛf.iː.eɪ.ɛl/
iron + aluminum alloy
Etymology
'Fe-Al' originates from chemical element symbols, specifically 'Fe' (from Latin 'ferrum') and 'Al' (from the English name 'aluminium', ultimately from Latin 'alumen').
'Fe-Al' changed from longer lexical forms like 'iron aluminide' or 'iron–aluminum alloy' into the concise chemical-form notation 'FeAl' and the hyphenated 'Fe-Al' used in materials science and engineering literature.
Initially, the components 'Fe' and 'Al' were simply the chemical symbols for iron and aluminium; over time the combined notation 'Fe-Al' came to be used as a shorthand referring specifically to iron–aluminum alloys or intermetallic phases.
