ʻO ka huila ʻana o Titanium Alloy
ʻO ia ka mea hoʻoheheʻe ʻāpana hoʻokahi i haku ʻia me ka solution solid β-phase. Me ka mālama ʻole ʻana i ka wela, ʻoi aku ka ikaika. Ma hope o ke kinai ʻana a me ka ʻelemakule, ʻoi aku ka holomua o ka alloy.One ka hoʻoikaika ʻana i ka ikaika, hiki i ka ikaika wela o ka lumi ke hiki i 1372 ~ 1666 MPa; Akā ʻaʻole pono ke hoʻohana ʻia i ka wela wela.
ʻO ia ka biphasic alloy, loaʻa nā waiwai piha maikaʻi, kūpaʻa maikaʻi, paʻakikī maikaʻi, plasticity a me nā waiwai deformation wela kiʻekiʻe, hiki ke ʻoi aku ka maikaʻi no ka hoʻoili ʻana i ke kaomi wela, hiki ke kinai ʻia, ʻelemakule e hoʻoikaika i ka alloy. ʻO ka ikaika ma hope o ka mālama ʻana i ka wela ma kahi o 50% ~ 100% kiʻekiʻe ma mua o kēlā ma hope o ka annealing; ʻO ka ikaika wela kiʻekiʻe, hiki ke hana ma 400 ℃ ~ 500 ℃ wela no ka manawa lōʻihi, ʻoi aku kona kūpaʻa wela i ka α titanium alloy.
Ma waena o nā'āpana titaniumʻekolu,ʻo ka mea maʻamau i hoʻohanaʻia he α titanium alloy a me ka α+β titanium alloy; ʻO ka hana ʻoki ʻana o ka α titanium alloy ka mea maikaʻi loa, a ukali ʻia e α+β titanium alloy, a ʻo ka β titanium alloy ka mea ʻino loa. α titanium alloy code no TA, β titanium alloy code no TB, α+β titanium alloy code no TC.
Hiki ke hoʻokaʻawale ʻia ka huila Titanium i loko o ka mea wela wela, ka ikaika kiʻekiʻe, ka corrosion resistant alloy (titanium - molybdenum, titanium - palladium alloy, etc.) huila). Hōʻike ʻia ka hoʻohui ʻana a me nā ʻano o nā ʻāpana maʻamau i ka papa.
Hiki ke kiʻi ʻia nā ʻāpana ʻāpana like ʻole a me ka microstructure o nā alloys titanium i mālama ʻia ma ka hoʻoponopono ʻana i ke kaʻina hana wela. Manaʻo maʻamau ʻoi aku ka maikaʻi o nā hale equiaxed maikaʻi, ʻoi aku ka maikaʻi o ka plasticity, ka paʻa wela a me ka ikaika luhi. He kiʻekiʻe ka lōʻihi o ka spiculate structure, ka ikaika kolo a me ka paʻakikī haki. ʻOi aku ka maikaʻi o nā ʻiʻo i hui pū ʻia me ka equiaxial a me ka nila-like. ʻO Titanium kahi ʻano metala hou, ʻo ka hana o ka titanium e pili ana i ka ʻike o ke kalapona, nitrogen, hydrogen, oxygen a me nā mea haumia ʻē aʻe, ʻaʻole ʻoi aku ka maʻemaʻe o ka titanium iodide impurity ma mua o 0.1%, akā he haʻahaʻa kona ikaika, plasticity kiʻekiʻe. .
ʻO nā waiwai o 99.5% ʻoihana titanium maʻemaʻe e like me kēia: density ρ=4.5g/ cubic cm, wahi hoʻoheheʻe 1725℃, conductivity thermal λ=15.24W/(mK), ikaika tensile σb=539MPa, elongation δ=25%, ʻāpana hoemi ψ=25%, modulus elastic E=1.078×105MPa, paakiki HB195. ʻO ka nui o ka titanium alloy ka mea maʻamau e pili ana i 4.51g / cubic centimeter, 60% wale nō o ke kila, ʻo ka ikaika o ka titanium maʻemaʻe kokoke i ka ikaika o ke kila maʻamau, ʻoi aku ka ikaika o ka titanium alloy ma mua o ka ikaika o ka nui o ke kila kila. No laila, ʻoi aku ka nui o ka ikaika kikoʻī (ikaika/density) o ka alloy titanium ma mua o nā mea hana metala ʻē aʻe, e like me ka hōʻike ʻana ma ka Papa 7-1. Hiki iā ia ke hana i nā ʻāpana a me nā ʻāpana me ka ikaika ʻāpana kiʻekiʻe, ka rigidity maikaʻi a me ke kaumaha māmā. I kēia manawa, hoʻohana ʻia nā alloys titanium i nā ʻāpana ʻenekini, skeleton, ʻili, nā mea paʻa a me nā mea hoʻokele.
