Fa'avevela ma le pikiina
E pei o isi u'amea nickel, e tatau ona mama le alloy 690 a'o le'i fa'avevela ma e tatau ona fa'avevela i se siosiomaga maualalo-sulfur.E tatau fo'i ona fa'aiti'iititi fa'aitiitiga o le ogaumu mo le fa'avevela matala ina ia taofia ai le fa'ama'iina tele o mea.
INCONEL u'amea 690 o se u'amea solo-mausalī ma e le fa'ama'a'a i le fa'avevelaina.E masani ona fa'aaogaina le fa'ameamea i le tulaga fa'a'ele'ele.
Fausia
Ole fua ole vevela mo le vevela mamafa o le INCONEL alloy 690 ole 1900 i le 2250°F (1040 i le 1230°C).E mafai ona fai le fa'amalama i le vevela e o'o i le 1600°F (870°C).
Microstructure
INCONEL alloy 690 o se austenitic, solid-solution alloy ma se maualuga maualuga o le mautu o le metallurgical.O le u'amea e maualalo le soluble mo carbon, ma o lona microstructure e masani ona aofia ai carbide.O le carbide tele o loʻo i ai i totonu o le uʻamea o le M23C6;o le tele o le vaega e fesuisuiaʻi i le kaponi ma le vevela o mea.O isi vaega e masani ona iai o titanium nitrides ma carbonitrides.E leai ni vaega fa'afefeteina fa'atasi e pei o le sigma vase ua fa'ailoaina i le u'amea 690.
