Abstract
Inventia de fata se refera la un procedeu pentru obtinerea aliajelsor refrcatare de nichel înalt aliate, deformabile la cald, calibile, avînd rezistenta îmbunatatita la fluaj la temperaturi ridicate, destinate pentru confectionarea paletelor de turbine cu gaz. Procedeul prevede introducerea în sarja metalica cuprinzînd 25-80% Ni, 12-35% Cr, eventual maximum respectiv 20% Co, 55% Fe, 15% W, 10% Mo, 0,002-0,2% C 0,1+(6,5xN)% Zr, 0,01-0,02% Ce, 0,001-0,015% B si eventualele impuritati ocazionale a Nb, Ti, Al. în scopul realizarii unei akieri omogene a clementelor înalte respective cît si a folosirii simultane a afectului purifreatos al acestor elemente pentru topitura metalica si de îmbunatatire a rezistentei la fluajul aliajului care se obtine, se introduce în sarja de Ni-Cr de compozitie prestabilita, mentionata 1-6% Ti si sau maximum 8% Nb cît si 0,2-6& Al sub forma unui aliaj sw al -Mg astfel încît în topitura sa se asimileze pe lînga Ti, Nb, al, Mg în proportie de 0,01%-0,03% repartizat omogen.
