Huahana hoolei hao hina hina ma ka hoolei one

ʻO ka hao hina hina ka metala ferrous nona ka cementite decomposes i ka hao a me ke kalapona ma ke ʻano o ka graphite i kapa ʻia ʻo graphitization cast irons kahi i hoʻoheheʻe ʻia ka hapa nui o ka cementite e ka graphitization.

Nā hiʻohiʻona o ka hana ʻana o ka hao hina hina:
• He liʻiliʻi ka liʻiliʻi o ka hao hina wai, a liʻiliʻi ka liʻiliʻi o ka leo a me ka laina laina, a liʻiliʻi ka notch sensitivity.
• ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ka ikaika compressive e pili ana i 3 ~ 4 mau manawa kiʻekiʻe ma mua o ka ikaika tensile
• ʻO ka haʻalulu maikaʻi, ʻo ka haʻalulu o ka hao hina ma kahi o 10 mau manawa ʻoi aku ka nui ma mua o ke kila kila.
• He haʻahaʻa ka modulus o ka elasticity o ka hao hina

Nā hiʻohiʻona o ka hao hina hina:
• Loaʻa ka mānoanoa pā liʻiliʻi a me nā ʻano paʻakikī
• He liʻiliʻi ke koʻikoʻi koena o ka hoʻolei ʻana
• ʻAʻole pono e hoʻolālā ʻia ka hao hina hina me nā hale mānoanoa loa, a hoʻohana pinepine ʻia nā ʻāpana asymmetric e hoʻohana piha i ko lākou ikaika compressive.

Kaʻina hoʻolei onehāʻawi i ka ʻoi aku ka maʻalahi a me ka mea hana pono loa. Hoʻolako ʻia kā mākou hale hoʻoheheʻe one me kahi hale hana metallurgical piha e hoʻoholo ai i nā ʻano kemika a me nā ʻano mīkini o kēlā me kēia heheʻe a me ka nānā ʻana i ke kūlana metallugic o ka metala hehee ma mua o ka ninini ʻana. Nānā ʻia nā microsections ma lalo o ka microscope no ka loaʻa ʻana o ka ʻike hope loa e pili ana i ka hoʻolei ʻana. Hoʻopuka mākou i ka palapala hōʻoia 3.1 no kēlā me kēia ʻāpana i hāʻawi ʻia ma ke noi a ka mea kūʻai aku. ʻO nā hao hao he mau ferrous alloys i loaʻa nā mea kalapona i ʻoi aku ma mua o 2%. ʻOiai hiki ke loaʻa ka pākēneka kalapona i ka hao hao ma waena o 2 a 6.67, ʻo ka palena kūpono ma waena o 2 a me 4%. He mea nui kēia ma muli o kā lākou mau hiʻohiʻona maikaʻi loa. ʻO nā hao hina hina a me nā hao ductile (i kapa ʻia ʻo nodular cast iron a i ʻole spheroidal graphite iron).

ʻO kā mākou mau mea maikaʻi ma ke kahua hoʻolei one:
• He ʻumi makahiki o ka ʻike i ka hoʻolei ʻana i ke one, ka hoʻoheheʻe ʻana i ka pūpū a me ka ʻenehana mīkini.
• ʻO nā kiko kikoʻī pololei no nā hiʻohiʻona kūloko paʻakikī.
• Kūkākūkā nui e hoʻomaka ana ma ka pae hoʻolālā.
• Hoʻoponopono maikaʻi i loko o ke kaʻina hana a me ka hilinaʻi kaʻina kiʻekiʻe.

Nā mea hana hao hina:
ʻO kēia ka palapala noi maʻamau no kēlā me kēia degere o ka hao hina hina no kāu kuhikuhi.
