ʻO ka ʻokoʻa ma waena o ka ʻōwili anuanu a me ka ʻōwili wela

ʻO kaʻokoʻa ma waena o ka'ōwili anuanu a me ka'ōwili wela ka nui o ka mahana o ka'ōwili.ʻO ka "anu" ke ʻano o ka mahana maʻamau, a ʻo ka "wela" ʻo ia ka wela kiʻekiʻe.Mai ka manaʻo metallographic, pono e hoʻokaʻawale ʻia ka palena ma waena o ka ʻōwili anu a me ka ʻōwili wela e ka mahana recrystallization.ʻO ia hoʻi, ʻo ka ʻōwili ʻana ma lalo o ka mahana recrystallization ʻo ke anuanu ka ʻōwili ʻana, a ʻo ka ʻōwili ʻana ma luna o ka mahana recrystallization ʻo ka wela wela.ʻO ka mahana recrystallization o ke kila he 450 a 600°C. ʻO nāʻokoʻa nui ma waena o ka'ōwili wela a me ka'ōwili anu: 1. Keʻano a me ka maikaʻi o ka ili: No ka loaʻaʻana o ka pā anu ma hope o ke kaʻina hana o ka'ōwili wela o ka pā wela, a e hoʻokōʻia kekahi hoʻopauʻili i ka manawa like, ʻOi aku ka maikaʻi o ka ʻili o ka pā anu (e like me Surface roughness, etc.) ma mua o ka pā wela, no laila inā ʻoi aku ka kiʻekiʻe o ke koi no ka maikaʻi o ka uhi ʻana o ka huahana, e like me ka pena hope, koho ʻia ka pā anu, a wela. Hoʻokaʻawale ʻia ka pā i ka pā pickling a me ka pā non-pickling.He kala metala maʻamau ka ʻili o ka pā pickled ma muli o ka pickling, akā ʻaʻole i like ke kiʻekiʻe o ka ʻili e like me ka pā anu no ka mea ʻaʻole ia i ʻōwili anu.ʻO ka ʻili o ka pā unpickled maʻamau he ʻokiʻoki, kahi ʻeleʻele, a i ʻole kahi ʻeleʻele hao tetroxide.Ma ka ʻōlelo a ka poʻe kamaʻāina, me he mea lā ua kālua ʻia, a inā ʻaʻole maikaʻi ka ʻāina mālama, he ʻōpala liʻiliʻi kona.2. Hana: Ma keʻano laulā, ua manaʻo ʻia nā ʻano mechanical o ka pā wela a me ka pā anu i ʻike ʻole ʻia i ka ʻenekinia, ʻoiai ʻo ka pā anu i kekahi degere o ka hana paʻakikī i ka wā o ke kaʻina o ka ʻōwili anu, (akā, ʻaʻole ia e hoʻomalu. i nā koi koʻikoʻi no nā waiwai mechanical. , a laila pono e mālama ʻia ʻokoʻa), ʻoi aku ka kiʻekiʻe o ka ikaika o ka pā anuanu ma mua o ka pā wela, a ʻoi aku ka paʻakikī o ka ʻili, ma muli o ke ʻano o ka annealing. o ka papa anu.Akā ʻaʻole pili i ka annealed, ʻoi aku ka ikaika o ka pā anu ma mua o ka pā wela.3. Hoʻokumu i ka hana No ka mea ʻaʻole ʻokoʻa loa ka hana ʻana o nā pā anu a me ka wela, ʻo nā mea hoʻoikaika o ka hana ʻana e hilinaʻi ʻia i ka ʻokoʻa o ka maikaʻi o ka ʻili.No ka mea, ʻoi aku ka maikaʻi o ka ʻili mai nā pā anu, ʻo ka ʻōlelo maʻamau, ʻo nā pā kila o nā mea like me nā mea like., ʻoi aku ka maikaʻi o ka hopena o ka pā anu ma mua o ka pā wela.
