Khoom Parameters
Interstitial cov ntsiab lus xws li O, N, thiab C muaj feem cuam tshuam rau cov khoom siv ntawm cov khoom siv titanium. Thaum cov ntsiab lus ntawm interstitial ntsiab tsis tshaj qhov txwv sab sauv, cov ntsiab lus ntawm cov pa oxygen, nitrogen, thiab carbon muaj qhov cuam tshuam rau cov khoom siv ntawm titanium, tshwj xeeb tshaj yog lub zog tensile, yield zog, thiab Vickers hardness, uas qhia tau hais tias yuav luag linear nce nrog nce nyob rau hauv cov ntsiab lus, thaum lub yas elongation qhia ib tug tseem ceeb txo. Tsis tas li ntawd, qhov cuam tshuam ntawm cov khoom sib txawv ntawm cov khoom txo qis hauv qhov kev txiav txim ntawm N > O > C. Raws li qhia hauv Table 1.

Cov cheeb tsam thov
Nyob rau hauv aerospace teb, ntshiab titanium castings yog siv rau cov khoom tseem ceeb xws li cav hniav thiab compressor casings, uas yuav txo tau qhov hnyav thiab txhim kho kev ua tau zoo. Hauv kev kho mob, lawv tuaj yeem siv los tsim cov khoom cog xws li cov pob qij txha thiab lub plawv stents. Hauv kev lag luam chemical thiab marine engineering, ntshiab titanium castings tuaj yeem siv los ua corrosion- tiv thaiv cov khoom xws li li qub thiab lub cev twj tso kua mis. Tsis tas li ntawd, lawv kuj tau siv rau hauv cov khoom ua si, xws li golf club heads thiab tsheb kauj vab. Raws li pom hauv daim duab.
Khoom Paub meej
Cov qauv sib txawv muaj qhov sib txawv ntawm qhov siab tshaj plaws ntawm impurity ntsiab xws li O, N, C, thiab H hauv cov khoom siv titanium ntshiab, thiab cov kev sib txawv tshwj xeeb muaj nyob rau hauv Table 2. Vim tias qhov sib txawv ntawm impurity ntsiab muaj nyob rau hauv titanium daim txhuam cev, cov ntsiab lus impurity nyob rau hauv cam khwb cia ingots los ntawm txawv batches txawv me ntsis, ua rau kev sib txawv ntawm cov neeg kho tshuab. Tsis tas li ntawd, muaj kev sib raug zoo ntawm cov ntsiab lus ntawm impurity ntsiab thiab seb cov khoom siv ntawm cov ntshiab titanium castings ua tau raws li cov qauv. Yog li ntawd, nyob rau hauv qhov tseeb zus tau tej cov ntshiab titanium castings, nws yog ib qho tsim nyog yuav tau kawm txog cov nyhuv impurity xws li O, N, C, thiab H ntawm cov khoom siv ntawm cov ntshiab titanium castings.
