I-Titanium Alloy Steel Plate
Inkcazelo emfutshane:
I-Titanium alloy steel plate yi-alloy eyenziwe nge-titanium njengesiseko kunye nezinye izinto ezongeziweyo.I-Titanium ineendidi ezimbini zeekristale ezilinganayo kunye ne-heterogeneous: isakhiwo esixineneyo esine-hexagonal ngezantsi kwe-882 ℃ α i-Titanium, i-cubic ephakathi komzimba ngaphezu kwe-882 ℃ β Titanium.
I-alloy ye-Titanium yi-alloy eyenziwe nge-titanium njengesiseko kunye nezinye izinto ezongeziweyo.I-Titanium ineendidi ezimbini zeekristale ezilinganayo kunye ne-heterogeneous: isakhiwo esixineneyo esine-hexagonal ngezantsi kwe-882 ℃ α i-Titanium, i-cubic ephakathi komzimba ngaphezu kwe-882 ℃ β Titanium.
Izinto ze-alloy zinokuhlelwa ngokweendidi ezintathu ngokusekelwe kwimpembelelo yazo kwiqondo lokushisa lokutshintsha kwesigaba:
① Izinzile α Izinto ezandisa ubushushu benguqu yesigaba α Izinto ezizinzileyo ziquka i-aluminium, i-carbon, i-oksijini kunye ne-nitrogen.I-Aluminiyam yeyona nto iphambili ye-alloying ye-titanium alloy, enempembelelo ebalulekileyo ekuphuculeni ubushushu begumbi kunye namandla aphezulu obushushu be-alloy, ukunciphisa ubunzima obuthile, kunye nokwandisa imodyuli e-elastic.
② Izinzile β Izinto ezithoba iqondo lobushushu besigaba β Izinto ezizinzile zinokwahlulwa zibe ziindidi ezimbini: isomorphic kunye ne-eutectoid.Iimveliso ezisebenzisa i-titanium alloy 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 zinefuthe elincinci kwiqondo lokushisa lokutshintsha kwesigaba.I-oksijini, i-nitrogen, i-carbon, kunye ne-hydrogen zezona zinto zingcolileyo kwi-alloys ye-titanium.I-oksijeni kunye ne-nitrogen kwi-α Kukho i-solubility ephezulu kwisigaba, esinempembelelo enkulu yokomeleza kwi-titanium alloys, kodwa iyanciphisa iplastiki.Umxholo we-oksijeni kunye ne-nitrogen kwi-titanium idla ngokuchazwa ukuba ibe ngaphantsi kwe-0.15 ~ 0.2% kunye ne-0.04 ~ 0.05%, ngokulandelanayo.I-Hydrogen kwi-α I-solubility kwisigaba iphantsi kakhulu, kwaye i-hydrogen eninzi echithwe kwi-titanium alloys inokuvelisa i-hydrides, eyenza i-alloy brittle.Umxholo we-hydrogen kwi-titanium alloys idla ngokulawulwa ngaphantsi kwe-0.015%.Ukunyibilika kwe-hydrogen kwi-titanium kunokubuyiselwa umva kwaye kunokususwa ngokufunxa i-vacuum annealing.
