Ke Kaʻina Hana Hoʻomākaukau Laʻana Metallographic o nā Alloys Aluminum a me nā Aluminum a me nā Lako Hana Hoʻomākaukau Laʻana Metallographic

Hoʻohana nui ʻia nā huahana alumini a me ka alumini i ka hana ʻoihana, a he ʻokoʻa loa nā koi o nā kahua noi like ʻole no ka microstructure o nā huahana alumini. No ka laʻana, ma ke kahua aerospace, hoʻonohonoho ke kūlana AMS 2482 i nā koi maopopo loa no ka nui o ka palaoa a me nā ana o ka mea paʻa; i nā radiators kaʻa, aia nā koi koʻikoʻi no ka porosity o nā ʻāpana alloy alumini. No laila, ʻo ke kumu o ka nānā ʻana i ka metallographic e hoʻoholo inā kūpono kahi huahana ma ka nānā ʻana i kāna microstructure.

Hoʻohana ka loiloi metallographic i kahi microscope optical e nānā a hoʻopaʻa i kanā ʻano o ka microstructure o ka alumini a me nā mea hoʻohuihui alumini, e like me ka nui o ka palaoa, ke ʻano, a me ke ʻano like, i mea e hoʻoholo ai i ka ikaika a me ka plasticity o ka mea. Hiki ke hoʻohana ʻia e kālailai i ka nui, ka nui, ke ʻano, a me nā waiwai ʻē aʻe o nā pae lua. I ka wā o ke kaʻina hana nānā ʻana, aia nā koi no ka hoʻopau ʻana o ka ʻili a me ka palahalaha o ka workpiece. ʻO ka maʻamau, pono ka hoʻomākaukau ʻana i ka laʻana metallographic ma mua o kahi hoʻāʻo loiloi metallographic e hoʻopau i ka hōʻino ʻana o ka ʻili, e hōʻike i ke ʻano metallographic maoli o ka workpiece, a e hōʻoia i ka pololei o ka ʻikepili loiloi ma hope.

ʻO nā ʻanuʻu hoʻomākaukau laʻana no ka nānā ʻana i ka metallographic o nā huahana alumini alloy ma ke ʻano maʻamau, ʻo ia ka ʻoki ʻana i ka metallographic, ke kau ʻana, ka wili ʻana a me ka poli ʻana, a me ka pala. Pono kahi mīkini ʻoki metallographic no ke kaʻina hana laʻana, i lako me ka ʻōnaehana hoʻoluʻu wai e pale aku i ka deformation huahana, ka puhi ʻana o ka ʻili, a me ka hōʻino ʻana o ke ʻano i ka wā ʻoki.

No ke kaʻina hana kau ʻana, hiki ke koho ʻia ke kau ʻana wela a i ʻole ke kau ʻana anu e like me ka mea e pono ai; hoʻohana nui ʻia ke kau ʻana wela no nā huahana alumini maʻamau. I ka wā o ke kaʻina hana wili a me ka hoʻopili ʻana, ʻoiai he haʻahaʻa ka paʻakikī o nā huahana alumini, ʻo ka hoʻohana ʻana i ka pepa one kūpono a me ka lole hoʻopili i hui pū ʻia me ka wai hoʻopili hiki ke kōkua i ka hoʻokō ʻana i kahi ʻili laʻana maikaʻi aʻe a hiki i ka loaʻa ʻana o kahi ʻano aniani.

ʻO ka mea hope loa, no ke kaʻina hana ʻino, ua ʻōlelo ʻia e hoʻohana i kahi hopena ʻino alkaline akahai e pale aku i ka hōʻino ʻana i ka microstructure. Ma hope o ka ʻino ʻana, hiki ke waiho ʻia ka hāpana ma lalo o kahi microscope no ka nānā ʻana i ka metallographic.
