ʻO ka Annealing kahi hana wela o ka hoʻomehana ʻana i ke kila make i Ac3 (hypo-eutectoid steel) a i ʻole Accm (eutectoid a me hyper-eutectoid steel) ma luna o 30 ~ 50 ° C, e loaʻa ana i ka austenite, ka hoʻoluʻu ʻana i ka ea, a me ka mālama wela o kahi ʻano like ʻole. hana pearlite.
ʻO ke kumu o ka normalizing: ʻo ka normalizing o ke kila make e hoʻomaikaʻi i ka machinability, hoʻopau i nā hemahema hana wela, hoʻopau i ka carbide pūnaewele i ke kila make hypereutectoid, hoʻomākaukau no ka hoʻolālā annealing spheroidizing, a hoʻomaikaʻi i nā waiwai mechanical o ka make.
ʻO ka Annealing kahi kaʻina hana wela kahi e wela ai ke kila make i kahi mahana ma luna a ma lalo paha o ke kiko koʻikoʻi ʻo Ac1, a laila hoʻomaha mālie me ka wela o ka umu ma hope o ka mālama ʻana i ka wela e loaʻa ai kahi hoʻolālā kokoke-equilibrium.
ʻO ke kumu o ka annealing: ʻO ke kumu nui ka homogenize i ka haku mele a me ke ʻano o ke kila make, hoʻomaʻemaʻe i nā kīʻaha, hoʻoponopono i ka paʻakikī, hoʻopau i ke kaumaha a me ka hana paʻakikī, hoʻomaikaʻi i ka hana ʻana a me ka machinability o ke kila, a hoʻomākaukau i ke ʻano no ka quenching. .
Die steel annealing classification: ʻO nā ʻano o ka die steel annealing ʻo ia ka diffusion annealing, isothermal annealing, incomplete annealing, spheroidizing annealing, recrystallization annealing a me ke kaumaha hoʻomaha annealing.
