Ndi zotani Kuthetsa pafupipafupi?

Kuzimitsa ndi mtundu wa chithandizo cha kutentha, kuphatikiza kuzimitsa kwachiwopsezo, kuzimitsa kugunda kwamtima komanso kuzimitsa kwa isothermal.

Nthawi zambiri, kuzimitsa kumapangitsa kuti chogwirira ntchitocho chikhale ndi microstructure kuti zitsimikizire kuti gawo linalake limakwaniritsa zofunikira zamakina pambuyo pakutentha. Ikhoza kuwonjezera kuuma ndi mphamvu; onjezerani kukana kuvala.

Kuzimitsa kugunda ndikuwotcha chogwiritsira ntchito munthawi yochepa kwambiri (monga 1/1000 sekondi) mothandizidwa ndi mphamvu yayikulu ya kugunda, ndikuziziritsa mwachangu kwambiri, zomwe zimatha kupeza mbewu zabwino kwambiri komanso kuuma kwakukulu, osasintha, palibe filimu ya okusayidi, yosamva kuvala komanso yosawononga dzimbiri. Palibe kupsya mtima kumafunika pambuyo kuzimitsa.

Austempering ndi kutenthetsa workpiece ndi kutentha quenching, ndiyeno kuika mu ofunda mchere kusamba amene amachititsa dongosolo linalake kusintha kwa nthawi kupeza bainite ndi nyumba zina, kotero kuti ali ndi mphamvu apamwamba ndi toughness. Kupanikizika kozimitsa ndi kochepa, komwe kungalepheretse denaturation ndi kusweka. Oyenera magawo oonda komanso okulirapo.
