Ukushisisa kanye Pickling
Njengamanye ama-nickel alloys, i-alloy 690 kufanele ihlanzeke ngaphambi kokuba ishisiswe futhi kufanele ishiselwe endaweni enesulfure ephansi.Umkhathi wesithando somlilo wokushisa okuvulekile kufanele futhi unciphise kancane ukuvimbela i-oxidation ngokweqile yezinto.
I-INCONEL alloy 690 iyingxubevange yesisombululo esiqinile futhi ayiqini ngokwelashwa kokushisa.Ingxubevange ngokuvamile isetshenziswa esimweni annealed.
Ukubumba
Ibanga lokushisa lokwakheka okunzima okushisayo kwe-INCONEL alloy 690 lingu-1900 kuya ku-2250°F (1040 kuya ku-1230°C).Ukwakhiwa kokukhanya kungenziwa emazingeni okushisa afika ku-1600°F (870°C).
I-Microstructure
I-INCONEL alloy 690 iyingxubevange ye-austenitic, i-solid-solution enezinga eliphezulu lokuzinza kwe-metallurgical.I-alloy ine-solubility ephansi ye-carbon, futhi i-microstructure yayo ngokuvamile iqukethe ama-carbides.I-carbide enkulu ekhona ku-alloy yi-M23C6;ubuningi besigaba buyahlukahluka ngokuqukethwe kwekhabhoni kanye nokuchayeka okushisayo kwento.Ezinye izigaba ezivame ukuba khona yi-titanium nitrides nama-carbonitrides.Azikho izigaba ze-embrittling intermetallic ezifana nesigaba se-sigma ezikhonjwe ku-alloy 690.
