Annealing o ke anuanu huki paipu: e pili ana i ka metala mea wela i ka pono wela, mālama 'ia i kekahi manawa, a laila, lohi mālie wela kaʻina hana. Common annealing kaʻina: recrystallization annealing, stress annealing, spheroidizing annealing, piha annealing, etc.Annealing: ʻO ke kumu o ka mea nui e hōʻemi i ka paʻakikī o nā mea metala, hoʻomaikaʻi i ka plasticity, ka hana ʻana a me ka mīkini a me ke kaomi, a hoʻemi i ke koena o ke koʻikoʻi, hoʻomaikaʻi i ka hui a me ka hoʻohui ʻana o ka homogenization, a i ʻole no ka mālama wela ma hope o ka mākaukau no ka hui, etc.

ʻO ka hoʻopau ʻana i ka paipu kila huki anu: pili i ka wela i ke kila i ka Ac3 a i ʻole Ac1 wahi wela (ka kila) ma luna o kekahi mahana, mālama i kekahi manawa, a laila i ka wikiwiki hoʻomaha kūpono, e kiʻi i ka martensite bainite) (a i ʻole mālama wela. ʻO ke kaʻina hana o ka hui. ʻO nā hana hoʻopiʻi maʻamau e pili ana i ka ʻauʻau wai paʻakai, ka ʻauʻau martensite, ka austempering bainite, ka ʻili o ka ʻili a me ka quenching kūloko. a hoʻomākaukau no ka mālama ʻana ma hope o ka wela.
