Umehluko Phakathi Kwe-Cold Rolling kanye Nokuginqika Okushisayo Kumasu Okucubungula

Ukuginqika okushisayo nokubanda kwe-nickel{0}ama-alloys asuselwa ku-nickel kuyizinqubo ezimbili ezibalulekile zokugingqa, zombili zisebenzisa ukucubungula kwazo kwepulasitiki. Zihluke kakhulu ngokuya ngenqubo kanye nezici zomkhiqizo, futhi imisebenzi yazo iyahambisana.

I-Hot rolling yenziwa ngaphezu kwezinga lokushisa le-recrystallization (1000-1200℃). Isebenzisa ama-cast billets noma ama-billet omgunyathi njengezinto zokusetshenziswa, ibhekana nezinqubo ezifana ne-homogenizing annealing, heat, multi{11}pass rolling (ngokwehliswa kwephasi eyodwa ngo-10% -30% kanye nesivinini esingu-1-5 m/s), ukupholisa ngokushesha, kanye nokwehla. Inhloso yayo ukuqeda ukonakala, ukulungisa okusanhlamvu, nokugingqe amabhilidi abe yimikhiqizo ewugqinsi (Enkulu noma ilingana no-3mm) njengamapuleti aphakathi nendawo nasindayo kanye namabhilidi emigqa. Inezinzuzo zokuvumela ukuguquguquka okukhulu nokuthuthukisa izakhiwo zemishini ye-alloy. Kodwa-ke, inekhwalithi ephezulu ephansi kanye nokunemba kobukhulu (ngokubekezelela okungu-±0.5mm) kanye nezindleko eziphansi, okuyenza ifanelekele izimo ezifana nama-tube billets anezindonga eziwugqinsi zamajeneretha esitsha samandla enuzi.

Ukugoqa okubandayo kwenziwa ngaphansi kwezinga lokushisa lekristalu (izinga lokushisa legumbi - 200℃). Isebenzisa amapheshana ashisayo-agoqiwe noma amapuleti amancanyana njengamabhilidi, ngemva kokwelashwa okungaphezulu, idlula-i-pass rolling (nge-pass yehliswe ngo-5%-}20%, edinga ama-anealings amaningi amaphakathi ukuze kubuyiselwe ipulasitiki), okulandelwa ukugingqika, ukuqondisa, kanye nokwelashwa kokushisa okungase kube khona. Inhloso yayo ukunciphisa ukujiya, ukuthuthukisa ukunemba kohlangothi (ngokubekezelela kufika ku-±0.005mm) kanye nekhwalithi yendawo ephezulu, kanye nokuthuthukisa amandla ngokuqiniswa komsebenzi. Ingakhiqiza amapuleti amancane kanye{12}}nemicu emincane kakhulu (Ngaphansi noma elingana no-3mm). Ngezindleko eziphezulu, ifanele izingxenye ezinembayo ezifana{13}}nezinga lokushisa eliphezulu lama-aero-engines.
