Pehea e koho ai i nā pā Titanium
Pehea e koho ai i kahi pā titanium
Hiki ke hoʻokaʻawale ʻia nā mea hoʻohui i ʻekolu mau ʻāpana e like me kā lākou hopena i ka mahana hoʻololi o ka pae:
1. ʻO nā mea e hoʻokūpaʻa i ka māhele α a hoʻonui i ka mahana hoʻololi o ka pae he mau mea hoʻokūpaʻa α, e like me ke alumini, carbon, oxygen, a me ka nitrogen. I waena o lākou, ʻo ka alumini ka mea hoʻohui nui o ka titanium alloy, nona ka hopena i ka hoʻomaikaʻi ʻana i ka mahana maʻamau o ka alloy a me ka ikaika wela kiʻekiʻe, e hōʻemi ana i ka gravity kikoʻī, a me ka hoʻonui ʻana i ka modulus elastic.
2. ʻO ka mea e hoʻokūpaʻa i ka māhele β a hoʻemi i ka mahana hoʻololi o ka māhele,ʻo ia ka mea β-stabilizing element, hiki ke māheleʻia iʻeluaʻano: isomorphic a me eutectoid. ʻO nā huahana e hoʻohana ana i nā alloys titanium he molybdenum, niobium, a me ka vanadium; ʻO nā mea hope loa he chromium, manganese, keleawe, hao, a me ke silika.
3. ʻO nā mea i liʻiliʻi ka hopena i ka mahana hoʻololi ʻana he mau mea kūʻokoʻa, e like me Zr, Sn, etc.
ʻO ka oxygen, nitrogen, carbon a me ka hydrogen nā mea haumia nui i nā alloys titanium. ʻOi aku ka nui o ka solubility o ka oxygen a me ka nitrogen i ka māhele α, he hopena hoʻoikaika koʻikoʻi i ka titanium alloy, akā hoʻemi ia i ka plasticity. ʻO ka mea maʻamau i ʻōlelo ʻia ʻo ka oxygen a me ka nitrogen ma ka titanium ma lalo o 0.15-0.2% a me 0.04-0.05%. He liʻiliʻi loa ka solubility o ka hydrogen i loko o ka māhele α, a ʻo ka nui o ka hydrogen i hoʻoheheʻe ʻia i loko o ka titanium alloy e hoʻohua ai i nā hydride, kahi e hoʻoheheʻe ʻia ai ka alloy. ʻO ka maʻamau, mālama ʻia ka ʻike hydrogen i nā alloys titanium ma lalo o 0.015%. Hiki ke hoʻohuli ʻia ka hoʻoheheʻe ʻana o ka hydrogen i ka titanium a hiki ke hoʻoneʻe ʻia e ka annealing vacuum.
