Ungakuvimbela kanjani ukukhiqizwa kokucindezelwa kokucisha ngesikhathi sokupholisa imodeli ejwayelekile?

Ngakho-ke ukuvimbela kanjani ukukhiqizwa kokucindezeleka kokucisha ngesikhathiisisekelo sokunemba kwesikhunta esijwayelekileUkupholisa?
Ukushisa kufanele kusetshenziselwe ukuqeda ukucindezeleka, futhi ngemva kokucinywa kwamamodeli ajwayelekile, ubilise i-30 ~ 60min ngaphambi kokwelashwa okupholisa, ususa u-15% kuya ku-25% ukucindezeleka kokucisha, ukuqinisa i-aus eyinsalela, bese kwenziwa - 60 ° C ukwelashwa okupholisa okujwayelekile noma umkhuhlane ojulile. ukwelashwa -120 ° C.

Lapho izinga lokushisa liphansi, kulapho uguquko olusele lwe-austenite luyinombolo ye-martensite, kodwa akunakwenzeka ukuguqula. Imiphumela yokuhlola ibonisa ukuthi i-austenite eyinsalela ilandisa cishe ngo-2% kuya ku-5%, futhi inani elincane le-austenite esele lingenza ingcindezi ehamba kancane kanye ne-buffer. Njengoba i-austenite esele ithambile futhi iqinile, ingakwazi ukumunca kancane amandla okwanda okusheshayo kwamandla, isuse ingcindezi yoshintsho lwesigaba. Ngemuva kokwelashwa okubandayo, imodeli evamile ikhishwa emanzini ashisayo ukushisa izinga lokushisa, futhi ukucindezeleka kokwelashwa okubandayo okungama-40% -60% kungaqedwa. Lapho izinga lokushisa likhuphukela ekamelweni lokushisa, kufanele lincishiswe ngesikhathi ukuze kuqhutshekwe kuqedwe ukucindezeleka kokwelashwa okubandayo, ugweme ukwenza imifantu yokwelapha okubandayo, ukuzuza izicubu ezizinzile nokusebenza, ukuqinisekisa ukuthiisisekelo sokunemba kwesikhunta esijwayelekile azikhubazeki ngesikhathi sokugcinwa kanye nokusetshenziswa.
