I ka ʻoihana ʻoihana, ʻo nā waiwai o nā metala he mea nui loa. ʻO ka paʻakikī, brittleness, paʻakikī a me ka ikaika o ka maka he hopena pololei i kāna hana ʻoki, ola lawelawe a me nā hiʻohiʻona noi. Ma waena o kēia mau ʻano, ʻo ka pilina ma waena o ka brittleness a me ka paʻakikī. No laila, ʻoi aku ka maikaʻi o ka brittleness ʻoi aku ka paʻakikī a ʻoi aku ka palupalu o ka metala?
ʻO ka brittleness, ma ke ʻano he waiwai kino o nā metala, e hōʻike ana i ke ʻano o kahi mea e wāwahi maʻalahi ke hoʻokau ʻia i nā mana o waho. ʻO ka ʻōlelo maʻalahi, ʻoi aku ka haki ʻana o nā metala me ka haʻihaʻi kiʻekiʻe ke hoʻokau ʻia i ka hopena a i ʻole ke kaomi. Ua like kēia me nā mea palupalu e like me ka hao hoʻolei, ka mea maʻamau i loaʻa i ko mākou ola i kēlā me kēia lā, a he mea maʻalahi ka haki ʻana i ka wā e hoʻokau ʻia ai i nā mana o waho.
ʻO ka paʻakikī naʻe, pili i ka hiki i kahi mea ke pale aku i kahi mea paʻakikī i kaomi ʻia i loko o kona ʻili. ʻO ia kekahi o nā hōʻailona hana koʻikoʻi o nā mea metala a ua ana pinepine ʻia ma nā ʻōlelo o nā pae hoʻohālike e like me HRC, HV a me HB. Ma ke kahua o nā ʻāpana ʻoihana, ʻo ke kiʻekiʻe o ka paʻakikī e hoʻoholo pololei i ka hiki ke ʻoki a me ke kūpaʻa ʻana o ka maka. ʻO ke kiʻekiʻe o ka paʻakikī, ʻoi aku ka paʻakikī o ka ʻili o ka ʻili e ʻoki ʻia a komo ʻia paha, e kūpono ai no ka ʻoki ʻana i nā mea paʻakikī.
No laila, aia kahi pilina ma waena o ka brittleness a me ka paʻakikī? Ma kekahi ala, hana ia. ʻO nā mea ʻoi aku ka paʻakikī, ʻoi aku ka paʻa o nā mea paʻa ma waena o nā ʻātoma i loko o ia mau mea, ʻo ia ka hopena i nā mea paʻakikī ke hoʻololi i ka plastically ke hoʻokau ʻia i nā mana o waho a ʻoi aku ka haki ʻana. ʻO ka hopena, ʻoi aku ka palupalu o nā metala paʻakikī.
Akā naʻe, ʻaʻole kēia manaʻo he ʻoi aku ka paʻakikī o kahi metala me ka brittleness kiʻekiʻe. ʻO ka ʻoiaʻiʻo, ʻo ka paʻakikī a me ka brittleness ʻelua mau nui kino like ʻole, a ʻaʻohe pilina kumu kūpono ma waena o lākou. Hōʻike mua ka paʻakikī i ka hiki ʻana o kahi mea ke pale aku i ke kaomi ʻana i loko o ka honua o waho, ʻoiai ʻo ka brittleness ka mea e hōʻike ana i ke ʻano o ka haki ʻana o kahi mea i ka wā i hoʻopili ʻia i nā mana o waho.
I kaʻoihana pahi ʻoihana, Pono e kaupaona ʻia ke koho ʻana o ka metala me ka paʻakikī a me ka brittleness ma muli o ke ʻano o ka noi kikoʻī. No ka laʻana, no nā lau i hoʻopaʻa ʻia i ka ʻoki wikiwiki kiʻekiʻe a me nā wahi wela kiʻekiʻe, koho pinepine ʻia ka paʻakikī kiʻekiʻe a me ka ʻaʻahu ʻana i ka HSS a i ʻole carbide. ʻOiai ʻoi aku ka kiʻekiʻe o ka brittleness o kēia mau mea, hiki iā lākou ke mālama i ka hana ʻoki maikaʻi a me ke ola lawelawe ma lalo o nā kūlana ʻoki kikoʻī.
No kekahi mau lau e pono ai ke kū i ka ikaika o ka hopena a i ʻole pono e kulou mau, e like me nā ʻili a i ʻole nā ʻoki, pono ʻoe e koho i kahi metala me ka ʻoi aku ka paʻakikī a me ka haʻahaʻa haʻahaʻa. E hōʻoia kēia ʻaʻole maʻalahi ka haʻihaʻi ʻana o ka maka i ka wā e hoʻokau ʻia ai nā mana o waho, a laila e hoʻolōʻihi i kona ola lawelawe.
ʻO ka hōʻuluʻulu manaʻo, ʻaʻole kūlike wale ka pilina ma waena o ka brittleness a me ka paʻakikī no nā metala ma ka ʻoihana ʻenehana. Ke koho ʻana i nā mea lau, pono e noʻonoʻo pono i nā ʻano o ka paʻakikī, brittleness, paʻakikī a me ka ikaika e like me nā hiʻohiʻona noi kikoʻī, i mea e hoʻokō ai i ka hopena ʻoki maikaʻi loa a me ke ola lawelawe.
