Sida Loo Doorto Taarikada Titanium
Sida loo doorto saxan titanium
Walxaha Alloying waxa loo qaybin karaa saddex qaybood iyadoo loo eegayo saamaynta ay ku leeyihiin heerkulka kala-guurka wejiga:
1.Waxyaabaha xasiliya wejiga α oo kordhiya heerkulka kala-guurka wejiga waa curiyeyaasha α xasilinta, sida aluminium, carbon, oxygen, iyo nitrogen. Waxaa ka mid ah, aluminiumku waa sheyga ugu muhiimsan ee daawaha titanium, kaas oo leh saameyn muuqata oo lagu hagaajinayo heerkulka caadiga ah ee alloy-ga iyo xoogga heerkulka sare, yareynta cufnaanta gaarka ah, iyo kordhinta moodeelka laastikada.
2. Curiye xasiliya wejiga β oo yareeya heerkulka kala-guurka wejiga waa curiyaha β-dejinta, kaas oo loo qaybin karo laba nooc: isomorphic iyo eutectoid. Alaabooyinka isticmaalaya aluminiumka titanium waxaa ka mid ah molybdenum, niobium, iyo vanadium; kuwa dambe waxaa ka mid ah chromium, manganese, copper, iron, iyo silicon.
3. Walxaha saameyn yar ku leh heerkulka kala-guurka wajiga waa walxo dhexdhexaad ah, sida Zr, Sn, iwm.
Ogsajiinta, nitrogen, kaarboon iyo hydrogen ayaa ah wasakhda ugu weyn ee ku jirta alloys titanium. Ogsajiinta iyo nitrogen waxay leeyihiin milmayn weyn oo ku jira wajiga α, taas oo saameyn weyn ku leh xoojinta titanium alloy, laakiin waxay yareysaa caagagga. Caadi ahaan waxaa lagu qeexaa in Ogsajiinta iyo nitrogen-ka ku jira titanium ay ka hooseyso 0.15-0.2% iyo 0.04-0.05% siday u kala horreeyaan. Solubility of hydrogen ee wajiga α waa mid aad u yar, iyo hydrogen aad u badan oo ku milmay aluminium titanium waxay soo saari doontaa hydrides, taas oo ka dhigi doonta daawaha jajaban. Guud ahaan, waxa ku jira hydrogen-ga ku jira aluminium titanium waxa lagu xakameeyaa wax ka hooseeya 0.015%. Kala dirida hydrogen ee titanium waa dib loo rogi karaa waxaana lagu saari karaa nadiifinta faakuumka.
