Kuchiza kutentha ndi njira yomwe imagwiritsidwa ntchito kwambiri pokonza zinthu zachitsulo, zomwe zimasintha mawonekedwe a microstructure ndi katundu wa zipangizo poyang'anira kutentha ndi kuzizira kwawo. Chithunzi cha gawo lachitsulo cha carbon equilibrium ndi chida chofunikira pophunzira malamulo osinthika a microstructure a zipangizo zachitsulo pa kutentha kosiyana. Ngakhale kudziwa bwino gawo la gawo la iron carbon equilibrium ndikothandiza kwambiri pantchito yochizira kutentha, kudziwa mbali iyi kokha sikokwanira.
Choyamba, chithunzi cha gawo la iron carbon equilibrium ndi tchati chomwe chimafotokoza mgwirizano wapakati pa kaboni ndi chitsulo. Zimasonyeza zotheka gawo zikuchokera ndi gawo kusintha zipangizo zitsulo pa kutentha osiyana ndi zili mpweya. Titha kuphunzira za mawonekedwe olimba a gawo, kusintha kwa kutentha kwa gawo, ndi kusintha kwa chitsulo pamatenthedwe osiyanasiyana kuchokera pamenepo. Izi ndizofunikira pakupanga ndi kuwongolera njira zochizira kutentha, chifukwa kutentha ndi kuziziritsa kosiyanasiyana kumatha kubweretsa ma microstructures osiyanasiyana ndi katundu wa zida.
Komabe, kuphunzira ntchito yochizira kutentha kumapitirira kuposa kumvetsetsa gawo la gawo la iron carbon equilibrium. Izi ndi mbali zingapo zomwe ziyenera kuzindikirika:
Kumvetsetsa malamulo osinthira magawo azitsulo: Kuphatikiza pa chithunzi cha iron carbon equilibrium phase, ndikofunikiranso kumvetsetsa magawo azitsulo zina. Zitsulo zosiyana zimasintha magawo osiyanasiyana pa kutentha kosiyana, ndipo pochiza kutentha, m'pofunika kumvetsetsa makhalidwe achitsulo chilichonse.
Kudziwa njira yochizira kutentha: Kuphunzira chithandizo cha kutentha kumafuna kudziŵa njira zosiyanasiyana zotenthetsera ndi kuziziritsa, monga kuziziritsa, kuziziritsa, kuzimitsa, etc. Njira iliyonse imakhala ndi kutentha, nthawi, ndi kuzizira kwapadera kuti mukwaniritse zofunikira zakuthupi.
Kumvetsetsa mgwirizano pakati pa bungwe ndi magwiridwe antchito: Kumvetsetsa mgwirizano pakati pa kapangidwe kazinthu ndi magwiridwe antchito ndiye maziko a chithandizo cha kutentha. Poyang'anira ma microstructure azinthu, amatha kukhala ndi makina abwinoko, kukana kwa dzimbiri, ndi zina.
Kudziwa njira zoyesera ndi kusanthula: Kuphunzira chithandizo cha kutentha kumafunanso kudziwa njira zina zoyesera ndi kusanthula, monga kuwunika kwa microscope ya metallographic, kuyezetsa kuuma, kuyesa kwamphamvu, ndi zina zotero. Njirazi zingatithandize kuwunika momwe zinthu zilili komanso momwe zinthu zilili, potero kukhathamiritsa chithandizo cha kutentha. ndondomeko.
Mwachidule, kudziwa bwino gawo la gawo la iron carbon equilibrium ndi gawo chabe la ntchito yochizira kutentha. Kuphatikiza pa kumvetsetsa magawo a magawo, ndikofunikiranso kudziwa bwino malamulo a kusintha kwa gawo lachitsulo, njira zochizira kutentha, mgwirizano pakati pa microstructure ndi katundu, komanso kuyesa ndi kusanthula njira. Pokhapokha podziwa bwino izi zomwe zingatheke kuti zotsatira zabwino zitheke pa ntchito yochizira kutentha ndikukwaniritsa zofunikira zosiyanasiyana.
