Ungazikhetha njani iipleyiti zeTitanium
Indlela yokukhetha ipleyiti ye-titanium
Izinto ze-alloying zinokwahlulwa zibe ziindidi ezintathu ngokwempembelelo yazo kwiqondo lobushushu besigaba:
I-1.Izinto ezizinzisa isigaba se-α kunye nokwandisa ubushushu benguqu yesigaba yi-α izinto zokuzinzisa, ezifana ne-aluminium, i-carbon, i-oksijini kunye ne-nitrogen. Phakathi kwazo, i-aluminiyam yeyona nto iphambili ye-alloy ye-titanium alloy, eneziphumo ezicacileyo ekuphuculeni ubushushu obuqhelekileyo be-alloy kunye namandla obushushu obuphezulu, ukunciphisa ubunzima obuthile, kunye nokunyusa imodyuli elastiki.
2. Isici esizinzisa isigaba se-β kunye nokunciphisa ubushushu benguqu yesigaba yi-β-stabilizing element, enokwahlulwa ibe ziindidi ezimbini: isomorphic kunye ne-eutectoid. Iimveliso ezisebenzisa i-titanium alloys ziquka i-molybdenum, i-niobium, kunye ne-vanadium; Ezokugqibela ziquka ichromium, manganese, ubhedu, intsimbi, nesilicon.
3. Izinto ezinempembelelo encinci kwiqondo lokushisa lokutshintsha kwesigaba zizinto ezingathathi hlangothi, ezifana neZr, Sn, njl.
Ioksijini, initrogen, ikhabhoni kunye nehydrogen zezona zinto zimdaka kwialloys yetitanium. I-oksijeni kunye ne-nitrogen zine-solubility enkulu kwisigaba se-α, esinempembelelo enkulu yokomeleza kwi-alloy titanium, kodwa iyanciphisa iplastiki. Ngokuqhelekileyo kuchazwe ukuba umxholo we-oxygen kunye ne-nitrogen kwi-titanium kufuneka ube ngaphantsi kwe-0.15-0.2% kunye ne-0.04-0.05% ngokulandelanayo. I-solubility ye-hydrogen kwisigaba se-α incinci kakhulu, kwaye i-hydrogen eninzi kakhulu echithwe kwi-titanium alloy iya kuvelisa i-hydrides, eya kwenza i-alloy brittle. Ngokuqhelekileyo, umxholo we-hydrogen kwi-titanium alloys ilawulwa ngaphantsi kwe-0.015%. Ukunyibilika kwe-hydrogen kwi-titanium kunokubuyiselwa umva kwaye kunokususwa ngokufunxa i-vacuum annealing.
