Ukuqamba mahhalainsimbi inezindawo ezintathu ezilandelayo ezibalulekile ngaphansi kwesimo sokucisha.
(1) Izici zesakhiwo
Ngokusho kobukhulu bensimbi, ukushisa okushisa, isikhathi, izici zokuguqulwa kanye nemodi yokupholisa, isakhiwo sensimbi esicishiwe kufanele sihlanganiswe ne-martensite noma i-martensite + i-austenite esele, ngaphezu kwalokho, kungase kube ne-carbide encane engancibilikisiwe.Kokubili i-martensite kanye ne-austenite eyinsalela kusesimweni sokumetastable ezingeni lokushisa legumbi, futhi kuvame ukushintshela esimweni esizinzile se-ferric mass plus cementite.
(2) Izici zokuqina
Ukuhlanekezela kwe-lattice okubangelwa ama-athomu ekhabhoni kuvezwa ubulukhuni, okwanda nge-supersaturation, noma okuqukethwe kwekhabhoni.Ukucisha ubulukhuni besakhiwo, amandla aphezulu, ipulasitiki, ukuqina okuphansi.
(3) Izici zokucindezeleka
Kubandakanya ukucindezeleka okuncane nokucindezeleka okukhulu, okokuqala kuhlobene nokuhlanekezela kwe-lattice okubangelwa ama-athomu e-carbon, ikakhulukazi nge-carbon martensite ephezulu ukuze kufinyelele inani elikhulu kakhulu, ukuhlaziywa kwe-quenching martensite esimweni sokucindezeleka esishubile;Lokhu kokugcina kungenxa yomehluko wokushisa owenziwe engxenyeni yesiphambano lapho ucisha, indawo yokusebenza noma isikhungo sesimo sokucindezeleka sihlukile, kukhona ukucindezeleka okuqinile noma ukucindezeleka okucindezelayo, ku-workpiece ukuze ugcine ibhalansi.Uma ukucindezeleka kwangaphakathi kwezingxenye zensimbi eziqinile kungaqedwa ngesikhathi, kuzodala ukuguqulwa okuqhubekayo ngisho nokuqhekeka kwezingxenye.
Ukufingqa, nakuba i-workpiece ecishiwe inobunzima obuphezulu namandla aphezulu, kodwa idolo likhulu, isakhiwo asizinzile, futhi kukhona ukucindezeleka okukhulu kwangaphakathi okucishiwe, ngakho-ke kufanele kuthukutheliswe ukufaka isicelo.Ngokuvamile, inqubo yokushisa iyinqubo yokulandela yokucisha insimbi, futhi iyinqubo yokugcina kakhulu yenqubo yokulahla okushisayo, inikeza i-workpiece ngemva kwesidingo somsebenzi.
Ukushisa kuyinqubo yokushisisa insimbi eqinile ibe izinga lokushisa elithile elingaphansi kwe-Ac1, ukuyigcina isikhathi esithile, bese uyipholisa ezingeni lokushisa elilingana negumbi.Izinjongo zayo ezibalulekile yilezi:
(1) lungisa ngokunengqondo ubulukhuni namandla ensimbi, uthuthukise ukuqina kwensimbi, ukuze ucezu lokusebenza luhlangabezane nezidingo zohlelo lokusebenza;
(2) isakhiwo esizinzile, ukuze i-workpiece ngesikhathi sokusebenza unomphela ingenzeki ukuguqulwa kwesakhiwo, ukuze kuqiniswe isitayela nobukhulu bomsebenzi;
Ukunciphisa ukucindezeleka kwangaphakathi kwe-workpiece kungancishiswa noma kuqedwe ukuze kuncishiswe ukuguqulwa kwayo nokuvimbela ukuqhekeka.
