ʻO ka wehewehe pōkole:

Hōʻike huahana:

E like me ka maʻiʻo o ka alloy element ua māhele ʻia i:

ke kila kila haʻahaʻa (ʻo ka nui o nā mea hao ma lalo o 5%),

Ke kila kila waena (5% -10% o ka nui o nā mea hoʻohuihui)

Ke kila kila kiʻekiʻe (ʻoi aku ke kiʻekiʻe o ka mea hao ma mua o 10%).

E like me ka hoʻohui ʻana o ka mea alloy i:

Ke kila Chromium (Cr-Fe-C)

Ke kila Chromium-nickel (Cr-Ni-Fe-C)

ʻO ke kila manganese (Mn-Fe-C)

Ke kila silikoni-mangane (Si-Mn-Fe-C)

ʻO ka mana o nā mea hoʻohui i nā mea hana o ke kila

1. Ka hopena o nā mea hao i ka hana hoʻoheheʻe kila
ʻO ka haʻahaʻa haʻahaʻa o nā laina paʻa a me ka wai a ʻoi aku ka liʻiliʻi o ka wahi wela crystallization, ʻoi aku ka maikaʻi o ka hana hoʻolei ʻana.ʻO ka mana o nā mea hoʻoheheʻe i ka hana hoʻolei ʻana e hilinaʻi nui ʻia i ko lākou mana ma ke kiʻi pae Fe-Fe3C.Eia kekahi, he nui nā mea, e like me Cr, Mo, V, Ti, Al, e hana i ka carbide melting point kiʻekiʻe a i ʻole oxide particles i ke kila, e hoʻonui ai i ka viscosity o ke kila, e hoʻemi i ka wai, a e hōʻino i ka hana hoʻolei.

2. ʻO ka mana o nā mea hoʻohui i ka mīkini palaki o ke kila
Hoʻokaʻawale ʻia ka hana palaki i ka hana wela a me ka hana anu.ʻO nā mea hoʻohui i loko o ka hopena paʻa, a i ʻole ka hoʻokumu ʻana o ka carbide (e like me Cr, Mo, W, etc.), hoʻomaikaʻi i ka pale ʻana o ka thermal deformation o ke kila a me ka emi nui o ka thermoplasticity a maʻalahi hoʻi e paʻi a haki.ʻOi aku ka ʻino o ke kaʻina hana wela o ke kila hao maʻamau ma mua o ke kila kalapona.

3. Ka hopena o nā mea hoʻoheheʻe ʻia i nā waiwai wili o ke kila
Hoʻomaikaʻi nā mea huila i ka quenability o ke kila, hoʻoikaika i ke kūkulu ʻia ʻana o ka ʻiʻo brittle (martensite), a lilo ka hana kuʻi ʻana i mea ʻino.Eia naʻe, loaʻa i ke kila ka liʻiliʻi o Ti a me V, hiki ke hoʻomaikaʻi i ka hana wili o ke kila.

4. ʻO ka mana o nā mea hoʻohui i ka hana ʻoki ʻoki kila e pili pono ana i ka paʻakikī o ke kila, kūpono ke kila no ka ʻoki ʻana i ka paʻakikī paʻakikī o 170 HB ~ 230 HB.ʻOi aku ka maikaʻi o ka ʻoki ʻana o ke kila hao maʻamau ma mua o ke kila kalapona.Eia naʻe, hiki i ka hoʻohui kūpono o S, P, Pb a me nā mea ʻē aʻe ke hoʻomaikaʻi nui i ka hana ʻoki ʻana o ke kila.

5. ʻO ka mana o nā mea hoʻohui i ka hana o ke kaʻina hana wela o ke kila
ʻO ka hana o ke kaʻina hana wela e hōʻike ana i ka paʻakikī o ka hoʻomaʻamaʻa wela kila a me ke ʻano o ka mālama wela.Hoʻopili nui ia i ka quenability, overheating sensitivity, tempering embrittlement a me ka oxidative decarbonization.He kiʻekiʻe ka quenability o ke kila Alloy, a hiki ke hoʻohana ʻia ke ʻano hoʻoluʻu lohi i ka wā e hoʻopau ai, hiki ke hōʻemi i ka deformation a me ka haʻihaʻi ʻana o ka mea hana.ʻO ka hoʻohui ʻana i ka manganese a me ke silika e hoʻonui i ka naʻau wela o ke kila.
