ʻO Tungsten Alloy kahi ʻano mea hoʻoheheʻe me ka tungsten metala hoʻololi (W) ma ke ʻano paʻakikī a me ka nickel (Ni), hao (Fe), keleawe (Cu) a me nā mea metala ʻē aʻe e like me ka pae hoʻopaʻa. Loaʻa iā ia ka thermodynamic maikaʻi, kemika a me ka uila a hoʻohana nui ʻia i ka pale aupuni, pūʻali koa, aerospace, aviation, automotive, medical, consumer electronics a me nā kula ʻē aʻe. Hōʻike nui ʻia nā waiwai kumu o nā tungsten alloys ma lalo nei.
1. Kiʻekiʻe kiʻekiʻe
ʻO ka Density ka nuipaʻa o kēlā me kēia ʻāpana leo o kahi mea a me kahi ʻano o kahi mea. Pili wale ia i ke ʻano mea a ʻaʻohe mea pili i kona nuipa a me ka nui. ʻO ka nui o ka tungsten alloy he 16.5 ~ 19.0g / cm3, ʻoi aku ia ma mua o ka pālua o ke kila. ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ka ʻike o ka tungsten a i ʻole ka haʻahaʻa o ka ʻike o ka metala paʻa, ʻoi aku ka kiʻekiʻe o ka nui o ka tungsten alloy; ʻO ka mea ʻē aʻe, ʻoi aku ka haʻahaʻa o ka paʻa o ka alloy. ʻO ka mānoanoa o 90W7Ni3Fe ma kahi o 17.1g/cm3, ʻo 93W4Ni3Fe ma kahi o 17.60g/cm3, a ʻo 97W2Ni1Fe ma kahi o 18.50g/cm3.
2. Kiekie hehee ai
ʻO ka helu heheʻe e pili ana i ka mahana e hoʻololi ai kekahi mea mai ka paʻa a i ka wai ma lalo o kekahi kaomi. He kiʻekiʻe ka helu heheʻe o ka tungsten alloy, ma kahi o 3400 ℃. 'O ia ho'i, he maika'i ke kūpale wela o ka mea hao a 'a'ole ma'alahi ke ho'ohehe'e.
3. Kiekie paakiki
ʻO ka paʻakikī e pili ana i ka hiki o nā mea waiwai ke pale i ka deformation indentation i hoʻokumu ʻia e nā mea paʻakikī ʻē aʻe, a ʻo ia kekahi o nā hōʻailona koʻikoʻi o ke kūpaʻa ʻana o nā mea. ʻO ka paʻakikī o ka tungsten alloy he 24 ~ 35HRC. ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ka ʻike tungsten a i ʻole ka haʻahaʻa o ka ʻike metala paʻa, ʻoi aku ka nui o ka paʻakikī o ka tungsten alloy a ʻoi aku ka maikaʻi o ke kūpaʻa ʻana; ʻO ka mea ʻē aʻe, ʻoi aku ka liʻiliʻi o ka paʻakikī o ka alloy, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana. ʻO ka paʻakikī o 90W7Ni3Fe ʻo 24-28HRC, ʻo 93W4Ni3Fe ʻo 26-30HRC, a ʻo 97W2Ni1Fe ʻo 28-36HRC.
4. maikaʻi ductility
ʻO ka Ductility e pili ana i ka hiki ke hoʻololi i ka plastic o nā mea ma mua o ka haki ʻana ma muli o ke kaumaha. ʻO ia ka hiki o nā mea hana ke pane i ke koʻikoʻi a me ka deform mau loa. Hoʻopili ʻia e nā kumu e like me ka ratio raw material a me ka ʻenehana hana. ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ka maʻiʻo tungsten a i ʻole ka haʻahaʻa o ka ʻike metala paʻa, ʻoi aku ka liʻiliʻi o ka elongation o nā alloys tungsten; ʻO ka mea ʻē aʻe, piʻi ka elongation o ka alloy. ʻO ka elongation o 90W7Ni3Fe he 18-29%, ʻo 93W4Ni3Fe ka 16-24%, a ʻo 97W2Ni1Fe ka 6-13%.
5. Ka ikaika tensile kiʻekiʻe
ʻO ka ikaika tensile ka waiwai koʻikoʻi o ka hoʻololi ʻana mai ka hoʻololi ʻana i ka plastic plastic deformation i ka deformation plastic concentrated o nā mea waiwai, a me ka hiki ke hoʻopaʻa nui ʻia o nā mea ma lalo o nā kūlana static. E pili ana i ka haku mele 'ana, ka ratio maka a me nā mea 'ē a'e. ʻO ka maʻamau, hoʻonui ka ikaika tensile o nā tungsten alloys me ka hoʻonui ʻana o ka ʻike tungsten. ʻO ka ikaika tensile o 90W7Ni3Fe ʻo 900-1000MPa, a ʻo 95W3Ni2Fe ʻo 20-1100MPa;
6. Hana maikaʻi i ka pale
ʻO ka hana pale pale e pili ana i ka hiki o nā mea hana ke pale i ka radiation. ʻO ka tungsten alloy he hana pale maikaʻi loa ma muli o kona kiʻekiʻe kiʻekiʻe. ʻO 60% kiʻekiʻe ka nui o ka tungsten alloy ma mua o ke kēpau (~ 11.34g / cm3).
Eia kekahi, ʻaʻohe mea ʻawaʻawa, pili i ke kaiapuni, non radioactive, haʻahaʻa haʻahaʻa hoʻonui hoʻonui haʻahaʻa a me ka conductivity maikaʻi.
