Indlela yokukhetha ipleyiti ye-titanium alloy

I-alloy ye-Titanium yi-alloy eyenziwe nge-titanium kunye nezinye izinto. I-Titanium ineendidi ezimbini zeekristale ezilinganayo kunye ne-heterogeneous: isakhiwo esine-hexagonal esondeleneyo ngaphantsi kwe-882 ℃ α i-Titanium, i-cubic ephakathi komzimba ngaphezu kwe-882 ℃ β Titanium. Ngoku makhe oogxa bethu beSebe leTekhnoloji yeRSM babelane ngendlela yokukhetha iipleyiti ze-titanium alloy

　　Iimfuno zobugcisa:

1. Ukwakhiwa kweekhemikhali ze-titanium alloy plate kuya kuhambelana namalungiselelo e-GB/T 3620.1, kwaye ukutenxa okuvumelekileyo kokwakheka kweekhemikhali kuya kuhambelana nemimiselo ye-GB/T 3620.2 xa uMfuni ephinda ehlola.

2. Impazamo evumelekileyo yobukhulu bepleyiti iya kuhambelana namalungiselelo akwiTheyibhile I.

3. Impazamo evumelekileyo yobubanzi nobude bepleyiti iya kuhambelana namalungiselelo akwiThebhile II.

4. Ikona nganye yeplate iya kunqunyulwa kwi-angle efanelekileyo ngokusemandleni, kwaye i-oblique cutting ayiyi kudlula ukuphambuka okuvumelekileyo kobude nobubanzi beplate.

Izinto ze-alloy zinokwahlulwa zibe ziindidi ezintathu ngokwempembelelo yazo kubushushu benguqu:

① ISigaba esizinzile α, izinto ezandisa ubushushu benguqu yesigaba α Izinto ezizinzile ziquka i-aluminium, i-carbon, i-oksijini kunye ne-nitrogen. I-aluminium yinto ephambili ye-alloy ye-titanium alloy, eneziphumo ezicacileyo ekuphuculeni amandla e-alloy kwiqondo lokushisa kunye nobushushu obuphezulu, ukunciphisa ubunzima obuthile kunye nokwandisa imodyuli e-elastic.

② ISigaba esizinzile se-β, izinto ezinciphisa ubushushu benguqu yesigaba zi-β Izinto ezizinzile zingahlulwa zibe ziindidi ezimbini: isomorphic kunye ne-eutectoid. Iimveliso ze-Titanium alloy zisetyenziswa. Eyangaphambili iquka i-molybdenum, i-niobium, i-vanadium, njl. Le yokugqibela ibandakanya ichromium, manganese, ubhedu, intsimbi, isilicon, njl.

③ Izinto ezingathathi hlangothi, ezifana ne-zirconium kunye ne-tin, zinempembelelo encinci kwiqondo lokushisa lokutshintsha kwesigaba.

Ioksijini, initrogen, ikhabhoni kunye nehydrogen zezona zinto zimdaka kwialloys yetitanium. I-oksijeni kunye ne-nitrogen kwi-α Kukho ukunyibilika okukhulu kwisigaba, esinempembelelo enkulu yokomeleza kwi-titanium alloy, kodwa kunciphisa iplastiki. Ngokuqhelekileyo kuchazwe ukuba umxholo we-oksijini kunye ne-nitrogen kwi-titanium yi-0.15 ~ 0.2% kunye ne-0.04 ~ 0.05% ngokulandelanayo. I-Hydrogen kwi-α I-solubility kwisigaba incinci kakhulu, kwaye i-hydrogen eninzi kakhulu echithwe kwi-titanium alloy iya kuvelisa i-hydride, eyenza i-alloy brittle. Ngokuqhelekileyo, umxholo we-hydrogen kwi-titanium alloy ilawulwa ngaphantsi kwe-0.015%. Ukunyibilika kwe-hydrogen kwi-titanium kunokubuyiselwa umva kwaye kunokususwa ngokufunxa i-vacuum annealing.
