ʻO Ti6Al4V ka mea maʻamau a hoʻohana nui ʻia ka titanium alloy. Ti6Al4V Loaʻa ka ikaika kiʻekiʻe a me nā waiwai hoʻokumu maikaʻi, a hiki iā ia ke piʻi i ka ikaika ma luna o 1000 MPa.
ʻOi aku ka maikaʻi o ka hui biaxial o ka hui α+β, ʻoi aku ka maʻalahi o ka hana ʻana o ka pae β i loko o ka mahana deformation. ʻO ka vanadium, he mea hoʻokūpaʻa no ka māhele β, hiki ke hiki i ka pae β i loko o ka huila i nā kūlana wela. Hoʻonui kēia i ka ikaika wela o ka lumi ma kekahi ʻaoʻao a hoʻomaikaʻi i nā mea hana i nā mahana kikoʻī ma kekahi.
I loko o ka recrystallization o keia titanium huila Ti6Al4V, paʻa kemika nā pae ʻelua. hiki ke hoʻoikaika i ka hopena paʻa, akā ʻo ka TiAl precipitated phases i hana ʻia i ka wā ʻelemakule hiki ke hana i ka hoʻoikaika ʻana i ka ua, he mea nui loa ia. ʻO 550ºC ka wela hoʻoheheʻe ʻana o kēia mau haʻalulu, a ʻo ka mahana o ka wā kahiko maʻamau he 500ºC no 2-24 mau hola.
Maʻiʻo ʻeleʻele haumia maʻamau: O, 0.2; N, 0.04; H, 0.015; Cu, 0.35-1.0; Fe, 0.35-1.0 (wt.%). ʻO 4.54 g/cm3 ka mānoanoa o ka huila.
