Laulā o nā noi
Me kona mau waiwai kino maikai a me na pomaikai waiwai nui,hao ductileke lilo mālie nei i mea i koho ʻia ma nā ʻoihana ʻoihana he nui, e hoʻololi nui ana i nā mea kuʻuna e like me ke kila forged, steel stamped, weldments, malleable cast iron,hao hina hinaa me ke kila hoolei. Ma ʻAmelika Hui Pū ʻIa, ʻike maopopo ʻia kēia ʻano. Ua paʻa ka hao Ductile i kahi mahele nui o ka mākeke a ua hoʻololi maikaʻi ʻo ia i nā ʻāpana like ʻole o nā mea i ʻōlelo ʻia ma luna, e hōʻike ana i kona hiki ke hoʻohana like ʻole a me ka hoʻokūkū mākeke.
| Nā kahua noi | Hoolei ma'amau i ka hao hao | Nā ʻano hana | Papa |
| Paipu wai, kinoea a aila | ʻO nā paipu a me nā mea pono e hoʻolei Centrifugally, me ke anawaena i emi iho a i ʻole like me 2600 mm | ʻO ke kūpaʻa paʻi, ka pale ʻana i ka corrosion, ke kū ʻana o ke ōlaʻi a me ka pale lepo | |
| Nā kaʻa, nā kaʻa | Crankshaft, camshaft, koʻokoʻo hoʻohui, kaʻa, ka hale axle hoʻokele, ka pale pale kaulike, ka hale ʻokoʻa, etc. | Hiki ke pale i nā hawewe hopena ma -40°C | QT900-2 QT800-2 QT700-2 QT600-3 QT400-8 QT450-10 |
| Na moku, locomotives, diesel engines | Crankshaft, koʻokoʻo hoʻohui, pahu kāmeʻa, pahu, liner cylinder | Paʻa ʻaʻahu, kūpaʻa luhi, ikaika kiʻekiʻe | QT900-2 QT800-2 QT700-2 QT600-3 |
| Mekini mahiai | ʻO nā pou palau i hoʻohana ʻia e ka mīkini, nā ʻoʻo i hoʻohana ʻia e ka mīkini, nā uhi o ka lāʻau, nā mea ʻohi, nā kiaʻi maka, nā mea hana. | ʻO ka paʻakikī kiʻekiʻe, ke kū'ē i ka ukana hopena | QT400-15 QT450-10 QT500-7 |

Ke kālailai haku mele
Mai ka hiʻohiʻona o ka hoʻolālā hana, ʻo ka hana ʻana o ka hao ductile i hoʻomalu ʻia e ka ferrite matrix, helu ʻia no 60% o ka huina o ka puka, aʻo ka pearlite matrix e hahai kokoke ana ma hope a noho i kahi. Eia kekahi, ʻo ka matrix hui ʻia o ka ferrite a me ka pearlite pū kekahi no ka hapa nui. ʻO nā mea ʻekolu i hui pū ʻia ma kahi o 95% o nā hana hao ductile a pau, e hōʻike ana i ke kūlana mana o kēia mau matrices ʻelua i ka hana ʻana i ka hao ductile.
Ke kālailai waiwai mechanical maikaʻi
ʻO ke kumu nui e hiki ai i ka hao ductile ke kū i waho ma waena o nā mea he nui i loko o kāna mau ʻano mechanical kūikawā. ʻAʻole loaʻa kahi kiko i ka manaʻo kuʻuna, a hōʻike ke koʻikoʻi koʻikoʻi i nā hiʻohiʻona gradient mau ma luna o ka palena kaulike. Loaʻa kēia hiʻohiʻona mai ke ʻano kūʻokoʻa o nā pōpō graphite ma lalo o ke koʻikoʻi: ke ʻoi aku ke koʻikoʻi ma mua o ka palena elastic, ʻoiai ke ʻike ʻia nā pōpō graphite he ʻāpana o ka matrix, ʻaʻole lākou e hoʻololi hou, e hana ana i nā āpau i ka ʻaoʻao longitudinal, e hopena i ka hoʻonui ʻana i ka leo. , a ʻaʻole hiki ke hoʻopaʻa ʻia kēia hoʻonui ʻia e ke kaomi ʻaoʻao.
Hoʻohālikelike hana me nā mea ʻē aʻe
Ka hao hina hina: Ma ka maʻamau, hoʻohana ʻia ka ikaika tensile wale nō ma ke ʻano he hōʻailona hana, a ʻo ka papa kiʻekiʻe he palena palena ʻole (350 MPa wale nō). ʻO ka hoʻohālikelike, hōʻike ka hao ductile i nā pōmaikaʻi nui i ka ikaika a me ka plasticity.
ʻO ka hao hoʻoheheʻe ʻia: ʻOiai he mau hōʻailona palaki kona, inā he hao ʻeleʻele, pearlite a i ʻole keʻokeʻo malleable hao, ʻaʻole i like ka maikaʻi o kāna mau mea hana me ka hao ductile.
Ke kila kila a me ke kila kila: ʻOiai he hana maikaʻi loa ia i ka elongation post-fracture a me ka paʻakikī o ka hopena, ʻaʻole maikaʻi ka ikaika e like me ka hao ductile, e hōʻike hou ana i ka ʻoi aku o ka hao ductile i nā noi kikoʻī.
