I-lateral strip ye-magnetic field induction heat annealing parameters yokwelashwa

Ukwelashwa kokufakwa kokufudumeza kokufudumeza kwamandla kazibuthe kusetshenziswa ikakhulu ekuvuseleleni ukufakwa kabusha kwemichilo yensimbi ekhabhoni ephansi ebandayo nokuncishiswa ukuqeda izinguquko ezincike esikhathini. Inhloso yokufakwa kabusha kwe-recrystallization ikakhulu ukuthuthukisa ubumbano nobulukhuni bomucu wensimbi. Inhloso yokuncishiswa kokuqeda into yokuguga kanzima ukugcina ipulasitiki nokuqina komugqa wensimbi.

Kunezindlela ezimbili zokwelashwa kwesiko zokuncisha umugqa wensimbi ephansi yensimbi. Enye ukuhlanganisa yonke ikhoyili yensimbi yensimbi esithandweni somlilo esivikelayo, futhi umjikelezo wokuncibilikisa wesithando ngasinye ngu-16 ~ 24h; okunye ukuqaqa ukunamathisela endaweni evikelayo yokuqinisa isithando somlilo, futhi isikhathi sokusebenza sifushane, kepha umucu wensimbi unenkinga yokuguga ngemuva kokufakwa. Ngaphezu kwalokho, lezi zinqubo ezimbili zokunciphiswa zinokuphazamiseka kokusetshenziswa kwamandla okuphezulu nokusebenza kahle okushisayo.

Ngawo-1970, abacwaningi bakwamanye amazwe basebenzise indlela yokufudumeza amandla kazibuthe anqamulelayo ukuze kutholwe umugqa wensimbi yekhabhoni oshubile obandayo, othole imiphumela ethile futhi wasetshenziswa ekukhiqizeni. Ithebula 9-3 likhombisa ukuphakelwa kwamandla kanye nezinqubo zenqubo yokuncishiswa kwemigqa ekhiqizwa yikhabhoni yensimbi engaphansi ebandayo eguquguqukayo ebandayo.

Ithebula 9-3 Umugqa wensimbi onqamula amandla kazibuthe wokungeniswa kwamandla kagesi kanye nemingcele yenqubo yokuqinisa

Inqubo yokwelashwa yokwengeza engu-200 ~ 320 ° C ebhalwe kuThebula 9-3 isetshenziselwa ukuqeda ubunzima bokuguga bemichilo yensimbi ezacile. Lapho umucu wensimbi ogoqwe ngamakhaza ubhekene nokwelashwa okusheshayo okuqhubekayo kokuncishiswa, ngenxa yokungabi nesikhathi esanele sokuvuselelwa kokufakwa kabusha kwesakhiwo, isakhiwo esihlanganisiwe esihlanganisiwe asizinzile kakhulu. Ngemuva kokugcinwa ekamelweni lokushisa, ukuguga kwemvelo (isb. Ukuguga kohlobo) kuzokwenzeka ngaphansi kwesenzo sokucindezeleka kwangaphakathi. I-Phenomenon. Ukutholakala kokuguga okuncane kuzonciphisa ubucwebecwecwe bensimbi futhi kukhuphule ukuqina kwayo, futhi ezimweni ezinzima kuzokwenza ukuthi umucu wensimbi uqhekeke. Ukuze kuncishiswe ubunzima bokuguga, indlela yokwelashwa yama-200 ~ 300 ° C wokushisa okuphansi okunciphisayo nokupholisa okusheshayo kuyamukelwa.
