Kusankha annealing ndondomeko malata mkuwa

The gawo kusintha kutentha kwapepala lamkuwakuchokera ku α→ α+ ε ndi za 320 ℃, ndiko kuti, kutentha kwa kutentha ndipamwamba kuposa 320 ℃, kapangidwe kake ndi gawo limodzi, mpaka kutentha mpaka 930 ℃ kapena mawonekedwe amadzimadzi, poganizira kugwiritsa ntchito zipangizo, digiri. wa makutidwe ndi okosijeni wa workpiece pambuyo Kutentha ndi processing weniweni wa workpiece pambuyo kutentha mankhwala ndi katundu wina.Kutentha kwa kutentha ndikokwera kwambiri, oxidation ya workpiece ndi yayikulu.Kutentha kumakhala kochepa kwambiri, mphamvu ya workpiece ndi elasticity ndipamwamba ndipo kulimba kwake mwachiwonekere sikukwanira, sikoyenera kupanga.

Chifukwa cha kuchuluka kwa ng'anjo, kuti likhale dithermal ndi kupeza mphamvu inayake ndi kulimba, kuti atsogolere wotsatira kupinda processing, aliyense ng'anjo workpiece kutentha ayenera kugwira za 2h, ndiye akhoza kukhala opanda kanthu ozizira mankhwala, Komanso akhoza kusiya workpiece mu tempering mbiya pang'onopang'ono kuzirala.Kawirikawiri, workpiece yokonzedwa imatha kudziwika ndi njira ziwiri.Chimodzi ndicho kuyang'ana mtundu wa workpiece, ndiko kuti, chogwiritsidwa ntchito kuchokera kumtundu wamkuwa woyambirira kupita ku mtundu wabuluu, chifukwa cha okosijeni ndi pamwamba pa workpiece kuti apange 2 ~ 3μm wandiweyani wa oxide wosanjikiza, wosavuta kugwa.

Chachiwiri, workpiece akhoza mwachindunji kukonzedwa ndi dzanja kupinda kusankha kusankha.Pamene kupinda, ngati akuona kuti workpiece ali ndi mphamvu zina ndi elasticity, komanso akhoza kupinda, ndiye annealing zotsatira zabwino, oyenera kupanga processing.M'malo mwake, mphamvu ndi elasticity ya workpiece pambuyo mankhwala ndi apamwamba, ndipo si kophweka kupinda ndi dzanja, kusonyeza kuti annealing mankhwala zotsatira zoipa, ndipo ayenera annealed kachiwiri.

Pofuna kukwaniritsa cholinga yunifolomu kutentha ndi makutidwe ndi okosijeni, malata mkuwa pepala workpiece zambiri si oyenera processing mu ng'anjo bokosi popanda oyambitsa zimakupiza.Mwachitsanzo, pansi pa chikhalidwe cha ng'anjo yofanana, workpiece imachitidwa mu ng'anjo ya bokosi popanda kuyambitsa fani ndi chitsime cha ng'anjo yokhala ndi fani yolimbikitsa.

Chophimba cha malata amkuwa chomwe chimagwiritsidwa ntchito ndi ng'anjo yamtundu wa bokosi chimakhala ndi kuwala kosiyana, mphamvu zambiri komanso kulimba kosakwanira, komwe kumakhala kovuta kupindika ndikukonzedwa.Pambuyo pochiza bwino ng'anjo ya ng'anjo ya mtanda womwewo wa workpiece, kuwala ndi yunifolomu, mphamvu ndi kulimba ndizoyenera, zomwe zimagwirizana ndi ntchito zogwirira ntchito.
