Ngesikhathi sokushisa okushisayo, i-billet ishiselwa ekushiseni okungaphezulu kwendawo ye-recrystallization yensimbi ngokufudumeza kokungeniswa noma esithandweni somlilo noma kuhhavini.

Lokhu kushisa okuphezulu kakhulu kuyadingeka ukuze kugwenywe ukuqina kwezinsimbi ngesikhathi sokuguqulwa. Ngenxa yokuthi insimbi isesimweni sepulasitiki, ingenziwa ibe yizimo eziyinkimbinkimbi. Izinsimbi zigcina i-ductility kanye nokuqina.

Izinga lokushisa elijwayelekile lokubumba elidingekayo esihlokweni esishisayo sezinsimbi ezahlukene yileli:

• Insimbi efika ku-1150 ° C

• Ingxubevange ye-Aluminium 360 kuya ku-520 ° C

• Ingxube yethusi 700 kuya ku-800 ° C

Ukuze wenze izinsimbi ezithile, njengensimbi ye-superalloy, kusetshenziswe isihloko esishisayo esibizwa nge-isothermal forging.

Lapha, i-die ishiselwa ezingeni lokushisa eliseduze ne-billet ukuze kugwenywe ukupholisa phezulu kwengxenye ngesikhathi sokubumba. Ukuqamba ngezinye izikhathi kwenziwa endaweni elawulwayo ukuze kuncishiswe ukwakheka kwesikali se-oxide.

Ngokuvamile, izingxenye eziyinkimbinkimbi zenziwa ukucasula okushisayo, ngoba kuvumela ukuthi impahla ikhubazeke esimweni sayo sepulasitiki, futhi insimbi kulula ukuyicubungula.

Izinto okufanele zicatshangelwe ukucasula okushisayo zifaka:

• Ukukhiqizwa kwezingxenye eziyinkimbinkimbi

• Izilinganiso zokunemba okumaphakathi neziphansi

• Ukucindezeleka okuphansi noma ukuqina komsebenzi ophansi

• Ukwakheka okusanhlamvu okufanayo

• Ukwenyuka kwe-ductility

Ifekthri yethu ikhiqizaamabhawodi we-hexosayizi abade nosayizi abakhulu abanobuchwepheshe obuqanjiwe obushisayo.
