Stainless simbi pombi iko zvino yakawedzera kushandiswa zvakanyanya, nekuda kwekunaka kwayo kwegora kwaita basa rakakosha mukuvaka engineering, mukuita kwekugadzira isu tinoda mhinduro yakasimba yestainless simbi chubhu kugadzirisa, chinangwa chikuru ndechekuwana imwe martensite kuwedzera. kuoma kwezvigadzirwa, ngatitarisei mhinduro yestainless simbi chubhu processing:
(1) Mushure mekugadzirisa mhinduro, inodziiswa kusvika ku (760±15) ℃, uye zviri mukati mekabhoni uye alloyed zvinhu mu austenitic 904L stainless simbi chubhu inodzikiswa nekuda kwekunaya kweCr23C6 carbide kubva ku austenitic 904L stainless simbi chubhu ye. 90min, kuitira kuti iyo Ms point inosimudzwa kusvika 70 ℃ uye yobva yatonhodzwa kusvika mukamuri tembiricha kuti iwane martensite + αferrite + yakasara austenitic chimiro.Iyo yakasara austenite yakaora nekuchembera pa510 ℃.
(2) mushure mekugadziriswa kwekushisa kwepamusoro uye kurapwa kwecryogenic, mhinduro yakatanga kupisa kusvika ku950 ℃ uye yakachengetwa kwe90min.Nekuda kwekuwedzera kweMs point, huwandu hushoma hwemartensite hunogona kuwanikwa mushure mekutonhora kusvika kune tembiricha yekamuri.Mushure meizvozvo, imwe huwandu hwemartensite hunogona kuwanikwa ne -70 ℃ kutonhora kurapwa uye kubata kwe8h.
(3) Mushure mekugadziriswa kwemhinduro neinotonhora deformation nzira, iyo martensite yakaumbwa ne904L isina musono chubhu inotonhora yakaremara pakamuri tembiricha.Huwandu hwemartensite hwakaumbwa ne904L isina musono chubhu panguva inotonhora deformation ine hukama neiyo deformation huwandu uye kuumbwa kwe904L Stainless simbi chubhu.
Idzi nzira nhatu dziri pamusoro dzinowanzo shandiswa Stainless simbi chubhu mhinduro kurapwa nzira tariro kuunza rubatsiro kwauri.
