Pehea e hoʻokaʻawale ai i ke kila ʻōwili wela mai ke kila ʻōwili anu?

Ke kila ʻōwili welaa mekila ʻōwili anuʻelua ʻano kila maʻamau i hoʻohana ʻia no nā kumu like ʻole ma nā ʻoihana like ʻole.
Hana ʻia ke kila kalapona ʻōwili wela a me ke kila kalapona ʻōwili anu i nā mahana like ʻole e hāʻawi iā lākou i nā waiwai kū hoʻokahi. Hana ʻia ke kila ʻōwili wela ma nā mahana ma luna o ke kiko recrystallization o ke kila, ma kahi o 1700°F, ʻoiai hana ʻia ke kila ʻōwili anu i ka mahana o ka lumi. Hāʻawi kēia mau ʻano hana like ʻole i kēlā me kēia ʻano kila i nā waiwai kū hoʻokahi a me ke ʻano.

ʻO ke ala maʻalahi loa e hoʻokaʻawale ai ma waena o ke kila ʻōwili wela a me ke kila ʻōwili anu, ʻo ia ka hoʻopau ʻana o ka ʻili. Ma muli o ke kūkulu ʻia ʻana o ka unahi oxide i ka wā o ke kaʻina hoʻomaʻalili, hāʻawi kēia unahi oxide i ke kila ʻōwili wela i kona ʻano ʻeleʻele a hina paha a me ke ʻano ʻino. ʻAʻohe unahi oxide ma ke kila ʻōwili anu, no laila he ʻoi aku ka laumania o ka ʻili a me kahi hiʻohiʻona maʻemaʻe a ʻālohilohi.

ʻO kekahi kumu hoʻokaʻawale ma waenakila kalapona haʻahaʻa i ʻōwili wela ʻiaa mekila kalapona haʻahaʻa i ʻōwili anu ʻiaʻo ia ko lākou mau ʻae ʻana i ka nui a me nā waiwai mechanical. ʻO ke kila i ʻōwili wela ʻia, ʻaʻole ia e pololei loa i ka nui a ʻaʻole like ka mānoanoa a me ke ʻano. Hana ʻia ke kila i ʻōwili anu ʻia i nā ʻae ʻana i ka nui, no laila ʻoi aku ka kūlike o ka mānoanoa a me ke ʻano.

Eia kekahi, ʻoi aku ka kiʻekiʻe o ka ikaika tensile a me ka yield o ke kila i ʻōwili anu ʻia ma mua o ke kila i ʻōwili wela ʻia, e kūpono ai no nā noi e pono ai kahi mea ikaika a pololei hoʻi. I ka hana ʻana, hoʻohana pinepine ʻia ke kila i ʻōwili wela ʻia no nā huahana kila nui a mānoanoa e like me nā alahao, nā I-beams, a me nā ʻāpana kūkulu, ʻoiai hoʻohana pinepine ʻia ke kila i ʻōwili anu ʻia no nā huahana liʻiliʻi a paʻakikī e like me nā ʻāpana kaʻa, nā mīkini, a me nā lako hao.
