Ukufudumeza kunye nokuPickling
Njengezinye iialloyi zenickel, i-alloy 690 kufuneka icoceke phambi kokuba ifudunyezwe kwaye kufuneka ifudunyezwe kwindawo enesulfure ephantsi.Imimoya ye-furnace yokufudumeza evulekileyo kufuneka icuthe kancinci ukuthintela i-oxidation egqithisileyo yezinto.
I-INCONEL i-alloy 690 yi-alloy-solution alloy kwaye ayinzima ngonyango lobushushu.I-alloy idla ngokusetyenziswa kwimeko ye-annealed.
Ukubumba
Uluhlu lwamaqondo obushushu obunzima bokwenza i-INCONEL alloy 690 yi-1900 ukuya kwi-2250 ° F (1040 ukuya kwi-1230 ° C).Ukwenziwa kokukhanya kunokwenziwa kumaqondo obushushu ukuya kutsho kwi-1600°F (870°C).
Microstructure
I-INCONEL alloy 690 yi-austenitic, i-solid-solution alloy enezinga eliphezulu lokuzinza kwe-metallurgical.I-alloy ine-solubility ephantsi ye-carbon, kwaye i-microstructure yayo ngokuqhelekileyo iqukethe i-carbides.I-carbide enkulu ekhoyo kwi-alloy yi-M23C6;ubuninzi besigaba buhluka kunye nomxholo wekhabhoni kunye nokuvezwa kwe-thermal yezinto.Ezinye izigaba eziqhele ukubakho zii-titanium nitrides kunye ne-carbonitrides.Akukho zigaba ze-embrittling intermetallic ezifana nesigaba se-sigma zichongiwe kwi-alloy 690.
