ʻO nā pahi kīhini ʻo Ruitai: ʻO kāu kumu kumu no nā pahi kīhini maʻamau i hoʻonohonoho ʻia mai Kina
ʻO ka hoʻokumu ʻana i nā hiʻohiʻona o nā pahi ʻo Damaseko ma muli o kāna kaʻina hana forging kūʻokoʻa a me ka ratio waiwai.
ʻO ka mea mua,ʻo nā mea maka no ka hanaʻana i nā pahi Damaseko he mau kila me nā mea kalapona likeʻole. Ma hope o ka ʻoki maikaʻi ʻana a me ka hoʻohālikelike ʻana, lilo kēia mau kila i mea kūpono no ka hana ʻana i nā nui. A laila, hoʻokomoʻia kēia mau kila i loko o ka umu wela wela a hoʻomehanaʻia i nā wela kiʻekiʻe, e lilo i mea palupalu a maʻalahi hoʻi e hana. I ka wā o ke kaʻina hana, hoʻohana ka mea ʻeleʻele i ka hāmare forging nui e pelu pinepine a hahau i nā mea maka, i lilo lākou i mea ʻole i ka pahi. ʻO kēia ʻano hana kuʻi pelu e hana i nā kila like ʻole e hōʻike i nā kala māmā a me nā kala ʻeleʻele ma nā pahi kaua i hoʻopau ʻia, ʻo ia ke ʻano nani a mākou e ʻike nei.
ʻOi aku ka maikaʻi o ke ʻano hana wili i hoʻohana mau ʻia i nā pahi Damaseko. ʻO kēia hana hoʻoheheʻe ʻana, ʻo ia ka pelu ʻana i nā ʻāpana he nui o nā kila like ʻole a wili iā lākou i ʻano ʻano wili, a laila hoʻopololei iā lākou i kahi ʻili palahalaha. Hiki i kēia hana forging ke hana i "nā laina wili", ʻo ia hoʻi, nā kaha a i ʻole nā ripple i hana ʻia e ka cementite i hoʻonohonoho ʻia ma ke ala wili. Hiki i ke ʻano wili ke hōʻike i nā ʻano like ʻole e like me ke kihi wili, ke kuhikuhi ʻana, ka helu wili a me nā mea ʻē aʻe, e like me nā laina pololei, nā nalu, nā laina spiral, nā laina hulu, etc.
Ma waho aʻe o ke kaʻina hana forging, ʻo ka ua a me ka hāʻawi ʻana i ka cementite i ka wā o ke kaʻina hana forging e pāʻani pū kekahi i ka hana nui i ka hoʻokumu ʻana i ke kumu. Hiki ke hoʻoheheʻe ʻia ka Cementite ma ka palena o ka palaoa austenite a i ʻole ke kumu eutectic, a hana i nā māhele spatial like ʻole me nā manawa a me nā ʻano hana hana ʻē aʻe, e hoʻonui ai i ke ʻano kumu.
Ma keʻano laulā, ʻo ka hoʻokumu ʻana o nā pahi Damaseko he kaʻina metallurgical paʻakikī, e pili ana i ka hoʻokaʻawale ʻana o nā mea he nui, ka hoʻololi ʻana o nā pae he nui a me nā hana forging he nui. ʻO kēia kaʻina hana kūikawā e loaʻa ai i kēlā me kēia pahi Damaseko kahi hiʻohiʻona kūʻokoʻa, lilo i mea waiwai kiʻi i waena o nā pahi.
