Indlela yokulawula ukuwohloka nokuqhekeka kwe imishini yokuqeda imvamisa ephezulu ngesikhathi sokukhulelwa

Ngenxa yomphumela ohlangene wokucindezeleka kwesakhiwo nokucindezeleka kokushisa, amathuluzi okusika insimbi enesivinini esikhulu avame ukukhubazeka futhi aqhekeke, futhi avelele kakhulu kumathuluzi okusika amakhulu, ayinkimbinkimbi futhi amancane.

Kunezizathu eziningi ze-deformation kanye nokuqhekeka, njengokucindezeleka okubandayo okusebenzayo kumathuluzi okusika ngaphambi kokwelashwa kokushisa, ukuqhekeka kwangempela, ukuhlukaniswa okujulile kwe-carbide, izinga lokushisa eliphezulu lokucisha imvamisa ephezulu kakhulu, ukupholisa okusheshayo, ukuhlanza ngaphambi kwesikhathi kanye nokushisa okungakafiki, njll. Uma ukuhlukaniswa kwe-carbide ensimbi yesivinini esiphezulu kudlula izinga elicacisiwe, ngokusobala kuzobangela ukuguqulwa nokuqhekeka. Ukuhlukaniswa kwe-carbides kuzodala ukuguquguquka nokuqhekeka, ngoba ngaphansi kwezimo ezithile zenqubo yokucisha, ingxenye enkulu yekhabhoni kanye nezinga le-alloying lapho ama-carbides afakwa khona aphakeme kunalawo akwezinye izindawo, ngakho-ke iphuzu likaNks liphansi, (eliphezulu Umshini wokushisela imvamisa) uholela ekuguqulweni kwe-austenite ibe yi-martensite ezifundeni ezahlukahlukene, okwandisa ukucindezeleka kwesakhiwo. Ukucindezeleka okubangelwayo, kungakhathaliseki ukuthi ngesikhathi sokucisha noma ukushisa, kungabangela ukuguqulwa noma ukuqhekeka kwendawo yokusebenza endaweni yokuhlukaniswa kwe-carbide.

Ukuze unciphise ukuguquguquka nokuqhekeka, izinto ezingavuthiwe kufanele zihlolwe ngokuqinile futhi izinga lokushisa lokucisha kufanele lilawulwe ngokuqinile. Ukuze kusetshenziswe amathuluzi okusika anezimo eziyinkimbinkimbi, kufanele kusetshenziswe izindlela eziningi zokushisa ukushisa kanye nezindlela eziningi zokuqeda, ezinganciphisa kakhulu ukuguqulwa kwamathuluzi okusika. Ngaphezu kwalokho, ama-clamps afanelekile angasetshenziswa ukulawula ukuguquguquka nokunciphisa ukuqhekeka.
