He aha ka elastic flat steel wire?

'Oloka'a 'ia ka uea kila pa'a i ka uea kila palahalaha e ka wili uea ki'eki'e ke anawaena palahalaha.He nui ka hoʻohana ʻana i ka uea kila palahalaha i ka hana ʻoihana, e like me ka ʻōnaehana alakaʻi aerospace a me ka uea kila pālahalaha i hoʻohana ʻia i ka ʻoihana koa, ka puna manawa, ka pahu wiper kaʻa a me nā mea hana lole e like me ke kāʻei lole nila, ka ʻohe a me ka ʻāpana kila.
Hiki ke loaʻa ka uea kila pālahalaha me ka laulā nui i ka mānoanoa a me ka pololei kiʻekiʻe ma ka ʻōwili ʻana i ke koʻokoʻo uea me kahi nui.

I kēia manawa, ʻo ka hoʻoheheʻe ʻana i ka uea kila pōʻai kekahi o nā ʻano hana nui no ka hana ʻana i ka uea kila pālahalaha kiʻekiʻe.I ka wā mua, ua loaʻa nui ka uea kila pālahalaha ma ke kaha anu.Ma muli o nā hemahema o ka ikaika kaha kaha kiʻekiʻe, nā koi lubrication kiʻekiʻe, nā poho koʻikoʻi a me nā mea ʻē aʻe, ua hoʻololi mālie ʻia e ke kaʻina ʻōwili paʻa o ka uea kila poepoe.ʻO ka uea kila palahalaha i loaʻa ma ke kaʻina hana ʻōwili palahalaha he hana maikaʻi loa, ka hana maʻalahi, ka maikaʻi o ka ʻili, ka mānoanoa like ʻole, a me ka ikaika tensile kiʻekiʻe ma hope o ka paʻakikī o ka hana anu.Ke hoʻohālikelike ʻia me ka uea kila palahalaha, he nui nā mea maikaʻi e like me ka haʻahaʻa haʻahaʻa haʻahaʻa hana hana, ka nui o ka pā paona nui a me ka hana kiʻekiʻe.

Ma hope o ka wela o ka uwea kookoo ua anu i ka kiko'ī nui, ua palupalu ia e ka recrystallization annealing, a laila, olokaa a me ka wela wela wela, a loaʻa nā huahana kūpono.Pono ke kaʻina holoʻokoʻa ma waena o ʻelua mau wela wela, ʻo ka hoʻomaʻamaʻa wela hope loa ma o ka hoʻopau ʻana i ka aila e loaʻa ai ka ikaika martensite, a laila koho i nā ʻano wela ʻokoʻa, e loaʻa ai ka pono mechanical pono.

Hoʻohana nui ʻia kēia kaʻina hana e nā mea hana nui, akā he mau hemahema pū kekahi, ʻo ia hoʻi:
(1) ke kaʻina hana lapaʻau waena e paʻakikī i ke kaʻina hana, hoʻemi i ka pono hana, hoʻonui i ke kumukūʻai hana a me ka poʻe hana;
(2) ma hope o ka mālama ʻana i ka wela waena, nalo loa ka hopena paʻakikī o ka hana i hana ʻia ma ke kaʻina hana kiʻi anu;
(3) ua kaupalena ʻia nā ʻano mechanical hope loa o ka huahana e ke kaʻina hana wela wela.
