ʻOi aku ka kiʻekiʻe o ka wela wela no nā alumini alumini ma mua o ka mahana annealing. ʻO ka ʻōwili wela kahi ʻano hana e pili ana i ka hoʻololi ʻana i ka plastik o ka metala ma nā mahana kiʻekiʻe e hoʻokō i ke ʻano a me nā waiwai i makemake ʻia.. ʻOi aku ka wela o ka ʻōwili wela ma luna o ka wela solidus o ka huila, e hōʻoia i ka plasticity lawa no ka deformation. No nā alumini alumini, e hāʻule maʻamau ka mahana ʻōwili wela i loko o kahi pae wela kiʻekiʻe, nui pinepine 500 degere Celsius, ma muli o ka haku mele a me nā waiwai.

Paʻa alumini/pepa kaʻina hana ʻōwili wela

Hoʻopili, ma ka lima ʻē aʻe, he kaʻina hana wela ma hope o ka ʻōwili wela (a i kekahi manawa ka hana anu) ʻo ia ka manaʻo e hoʻomaikaʻi i ke ʻano aniani a me nā waiwai o ka metala ma ka hoʻomehana ʻana iā ia i kahi mahana haʻahaʻa a laila hoʻomaha mālie, ma laila e hoʻopau ai i ke kaumaha o loko a hoʻonui i ka ductility. ʻOi aku ka haʻahaʻa o ka mahana annealing ma mua o ka wela o ka ʻōwili wela, maʻamau ma lalo o ka wela solidus o ka huila, a ʻokoʻa e pili ana i ka huila kikoʻī a me ka hana i makemake ʻia.

Aia ma lalo kahi papaʻaina maʻalahi e hōʻuluʻulu ana i nā mahana annealing no nā moʻo alumini alumini like ʻole. Manaʻo kēia papa e hāʻawi i kahi kuhikuhi wikiwiki i nā pae wela annealing maʻamau i kūpono no nā ʻano alumini alumini like ʻole. E hoomanao, ʻokoʻa paha ka mahana a me ke kaʻina hana ma muli o ka haku mele ʻana a me nā waiwai hope i makemake ʻia.

Hāʻawi kēia papa i kahi ʻike ākea. No nā kūlana annealing pololei, me ka manawa hoʻoluʻu a me ka helu hoʻoluʻu, e noiʻi i nā kikoʻī kikoʻī a i ʻole ka loea metallurgical. Hiki i nā koi kiko'ī ke hoʻopilikia nui i nā waiwai mechanical o ka mea a me ke kūpono no nā noi like ʻole.

ʻO ka hoʻopili ʻana i nā coils alumini he hana mālama wela maʻamau

Ma ka hōʻuluʻulu, ʻoi aku ka kiʻekiʻe o ka wela o ka ʻōwili wela ma mua o ka wela o ka annealing no ka mea ʻo ka ʻōwili wela e pono ai ka metala e lawa pono i ka plastic no ka deformation ma nā wela kiʻekiʻe., ʻoiai ʻo ka annealing e kālele ana i ka hoʻonui ʻana i ka hoʻolālā aniani a me nā waiwai a hana maʻamau i nā haʻahaʻa haʻahaʻa.
