Hoolei hao hina hina

ʻO ka hao hoʻoheheʻe hina (i kapa ʻia hoʻi ka hao hina hina) he pūʻulu hao hoʻoheheʻe ʻia me nā ʻano papa like ʻole e like me ka inoa ʻokoʻa o nā kūlana like ʻole. ʻO ka hao hao hina ke ʻano o ka hao kalapona a loaʻa kona inoa "hina" ma muli o ke ʻano o ko lākou ʻokiʻoki ʻana i ka hina. ʻO ka hana metallographic o ka hao hina hina ka mea nui i haku ʻia me ka flake graphite, metala matrix a me ka grain boundary eutectic. I ka wā o ka hao hina, aia ka Carbon i ka flake graphite. E like me kekahi o nā metala hoʻoheheʻe nui ʻia, hoʻolei ʻia ka hao hina he nui nā mea kōkua i nā kumukūʻai, castability a me ka machinablity.

Nā hiʻohiʻona hana oHoolei Hao Hina

• He liʻiliʻi ka liʻiliʻi o ka hao hina wai, a he liʻiliʻi ka liʻiliʻi o ka leo a me ka laina laina, a liʻiliʻi ka notch sensitivity.
• Haʻahaʻa haʻahaʻa haʻahaʻa mechanical waiwai, compressive ikaika e pili ana i 3 ~ 4 manawa kiʻekiʻe ma mua o tensile ikaika
• ʻO ka haʻalulu haʻalulu maikaʻi, ʻoi aku ka nui o 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 ʻano 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 asymmetrical e hoʻohana piha i ko lākou ikaika compressive.
