Abstract
Viene proposta una nuova lega ad alto titolo di oro alla quale è associato il tantalio in misura superiore al 2%, ottenuta preparando preventivamente una lega madre per ottenere una fase costituita da un componente complesso di Pd - Cu - Ta (palladio, rame, tantalio) finemente disperso in una matrice di metallo di percentuale prevalente costituita da Au - Pt - In - Ag (oro, platino, indio, argento) ed ottenendo una fase con cristalli di dimensioni 4-10 micron che costituisce una struttura di elevata durezza pari a 270 HV nello stato ottenuto dopo la fusione e di oltre 300 HV dopo una tempra a 500°C con mantenimento a tale temperatura per 15 minuti.
