Abstract
Viene insegnato un metodo per fornire migliorata duttilità in un alluminuro di titanio gamma. Il metodo implica aggiungere inclusioni di boro all'alluminuro di titanio contenente cromo e tantalio e lavorare termomeccanicamente il getto. Aggiunte di boro sono fatte in concentrazioni tra lo 0,5 e il 2% in atomi. Si trova una microstruttura a grani equiassiali fini dal getto solidificato. Si ottengono miglioramenti di proprietà mediante lavorazione termomeccanica.
