ʻO kā mākou huahana
apo wili no ka Mill
Nā pōmaikaʻi ʻenehana
He mea koʻikoʻi ka pale ʻana o nā mea wili.ʻO ka mea maʻamau, manaʻo ka poʻe he ʻoi aku ka paʻakikī o ka huahana, ʻoi aku ka hiki ke hoʻohana ʻia, no laila, nui nā foundries e hoʻolaha i kā lākou castings i loko o ka chromium, ʻo ka nui a hiki i 30%, a hiki i ka paʻakikī HRC i 63-65.Eia nō naʻe, ʻoi aku ka nui o ka hoʻopuehu ʻana, ʻoi aku ka nui o ka hana ʻana i nā micro-hole a me nā micro-cracks ma ke kikowaena ma waena o ka matrix a me nā carbide, a ʻoi aku ka nui o ka haki ʻana.A ʻoi aku ka paʻakikī o ka mea, ʻoi aku ka paʻakikī o ka ʻoki ʻana.No laila, ʻaʻole maʻalahi ka hana ʻana i ke apo wili paʻa a paʻa.Hoʻohana nui ʻia ke apo wili i nā ʻano mea ʻelua.
65Mn (65 manganese): hiki i kēia mea ke hoʻomaikaʻi nui i ka lōʻihi o ke apo wili.Loaʻa iā ia nā hiʻohiʻona o ka paʻakikī kiʻekiʻe, ke kūpaʻa maikaʻi maikaʻi a me ke kūpaʻa magnetism maikaʻi, hoʻohana nui ʻia i ke kahua hoʻoponopono pauka kahi e pono ai ka huahana e wehe i ka hao.Hiki ke hoʻomaikaʻi maikaʻi ʻia ke kūpaʻa ʻaʻahu a me ka paʻakikī e ka hoʻomaʻamaʻa ʻana a me ka mālama ʻana i ka wela.
Mn13 (13 manganese): ua hoʻomaikaʻi ʻia ka lōʻihi o ka hoʻolei ʻana i ke apo wili me Mn13 i hoʻohālikelike ʻia me 65Mn.Hoʻopili ʻia nā hoʻoheheʻe ʻana o kēia huahana me ka paʻakikī o ka wai ma hope o ka ninini ʻana, ʻoi aku ka ikaika o ka tensile kiʻekiʻe, ka paʻakikī, ka plasticity a me nā waiwai non-magnetic ma hope o ka paʻakikī o ka wai, e ʻoi aku ka lōʻihi o ke apo wili.Ke hoʻokau ʻia i ka hopena koʻikoʻi a me ka deformation ikaika ikaika i ka wā e holo ana, e hana ka ʻili i ka hana paʻakikī a hana i ka martensite, a laila e hoʻokumu ʻia ai kahi ʻāpana pale pale pale, mālama ka ʻili o loko i ka paʻakikī maikaʻi loa, ʻoiai inā ʻaʻahu ʻia i kahi ʻili lahilahi. hiki i ka wili wili ke kū i nā haʻawe haʻalulu nui aʻe.
