Abstract

Viene insegnato un metodo per fornire una migliorata colabilità in un alluminuro di titanio gamma. Il metodo implica aggiungere inclusioni di boro all'alluminuro di titanio contenente cromo e niobio. Aggiunte di boro sono fatte in concentrazioni tra lo 0,5 e il 2% in atomi. Una microstruttura a grani fini equiassiali si trova dal getto solidificato. Si ottengono anche miglioramenti di proprietà.
