Titanium Alloy Mechanical Properties
Kushandiswa kwetembiricha mazana mashoma madhigirii akakwira kupfuura aruminiyamu alloy, mukati tembiricha inogona kuramba ichichengetedza simba rinodiwa, inogona kuve 450 ~ 500 ℃ tembiricha kwenguva yakareba shanda aya maviri titanium alloy muhuwandu hwe150 ℃ ~ 500 ℃ ichine yakanyanya kusimba yakasimba, uye aruminiyamu alloy pa150 ℃ chaiyo simba yakadzikira zvakanyanya. Iyo tembiricha yekushandisa yetitanium alloy inogona kusvika 500 ℃, uye aruminiyamu alloy iri pazasi 200 ℃. Zvakanaka kupeta corrosion resistance.
Kudzivirirwa kwekuora kwetitanium alloy kuri nani kupfuura iyo yesimbi isina tsvina kana ichishanda mumhepo yakanyorova uye nepakati pemvura yegungwa. Kunyanya kurwisa kwakasimba kugomba ngura, kuonda kweasidhi uye kushushikana kwekuora mwoyo; Iyo ine yakanakisa ngura kuramba alkali, chloride, chlorinated organic zvinhu, nitric acid, sulfuric asidhi, etc. Zvisinei, titanium ine urombo ngura kuramba reductive okisijeni uye chromium munyu media.
Titanium alloy inogona kuchengetedza michina yayo pane yakaderera uye yakanyanya-yakaderera tembiricha. Titanium alloys ane yakanaka yakaderera tembiricha kuita uye yakaderera kwazvo interstitial zvinhu, senge TA7, inogona kuchengetedza imwe plasticity pa -253 ℃. Naizvozvo, titanium alloy zvakare yakakosha yakaderera tembiricha yemaitiro zvinhu. Chiitiko chemakemikari chetitanium chakakwirira, uye mhepo muO, N, H, CO, CO₂, mhute yemvura, ammonia uye mamwe maitiro akasimba emakemikari. Kana iyo kabhoni yemukati inopfuura 0.2%, ichaita yakaoma TiC mu titanium alloy;
Pakupisa kwepamusoro, kudyidzana neN kunoumbawo TiN yakaoma nzvimbo; Pamusoro pe600 ℃, titanium inotora okisijeni kuti iite dhiri rinoomesa nekuoma kwepamusoro; Iyo embrittlement layer ichaumbwa zvakare kana iyo hydrogen yemukati yasimuka. Kudzika kweiyo yakaoma brittle pamusoro inogadzirwa neinomwisa gasi inogona kusvika 0.1 ~ 0.15mm, uye iyo yekuomesa dhigirii i20% ~ 30%. Iyo kemikari inobatana yetitanium yakakura zvakare, iri nyore kugadzira adhesion neiyo friction surface.
Thermal conductivity yetitanium λ = 15.24W/ (mK) inenge 1/4 yenickel, 1/5 yesimbi, 1/14 yealuminium, uye kupisa kwemafuta emarudzi ose etitanium alloy inenge 50% yakaderera pane iyo. ye titanium. Iyo elastic modulus yetitanium alloy ingangoita 1/2 yesimbi, saka kuomarara kwayo kwakashata, kuri nyore kushandura, haifanirwe kugadzirwa netsvimbo yakatetepa uye yakatetepa-yakakomberedzwa zvikamu, kucheka kugadzirisa pamusoro rebound vhoriyamu yakakura, ingangoita 2 ~ 3 nguva. yesimbi isina tsvina, inokonzeresa kukweshana kwakanyanya, kunamatira, kupfeka kwekubatanidza mushure mekushandisa.
