Kub Ua Haujlwm Thiab Txias Ua Haujlwm Ntawm Titanium Alloys

Kub ua hauj lwm thiab txias ua hauj lwm, raws li ob tug tseem ceeb txoj kev tsim rautitanium alloys, nthuav tawm cov txheej txheem sib txawv ntawm cov yam ntxwv, kev ua tau zoo thiab kev siv cov xwm txheej raws li cov txheej txheem kub sib txawv thiab cov qauv deformation.

 

 

Qhov sib txawv tseem ceeb ntawm kev ua haujlwm kub thiab txias yog qhov ua haujlwm kub ntawm qhov ntsuas kub ntawm recrystallization. Nws ncaj qha txiav txim siab cov khoom siv microstructure thiab cov khoom.

 

Kub ua haujlwm: Ua los ntawm qhov kub ntawm recrystallization, nws tshem tawm kev ua hauj lwm hardening los ntawm dynamic recrystallization thiab enables yooj yim txoj kev.

 

Ua haujlwm txias: Ua nyob rau hauv chav tsev kub los yog qis dua qhov kub ntawm recrystallization, nws deforms ntawm dislocation slip nrog pom tseeb ua hauj lwm hardening thiab tsis muaj qhov tseem ceeb dynamic recrystallization.

 

 

(I) Kub Ua Haujlwm

Txhawm rau kom paub txog kev tsim cov loj- qhov loj me, tshem tawm raws li- nrum qhov tsis xws luag, txhim kho microstructure, txo deformation kuj thiab txhim kho kev tsim khoom.

 

Cov txheej txheem thiab cov yam ntxwv

Cov txheej txheem tseem ceeb: kub forging, kub dov, thiab kub extrusion.

 

Core tswj cov ntsiab lus

Ib puag ncig: Titanium alloys yog nquag oxidation thiab hydrogen embrittlement ntawm qhov kub thiab txias. Nws yuav tsum tau ua nyob rau hauv ib qho inert los yog lub tshuab nqus tsev ib puag ncig.

Kev hloov kub: nruj me ntsis tswj cov cua kub kub, tuav lub sij hawm thiab txias txias kom tsis txhob coarse nplej, plasticity tsis txaus los yog ntau dhau ntawm kev ntxhov siab.

 

Kev nyuaj

Coordinately tswj "kub, ib puag ncig thiab deformation", thiab daws cov teeb meem ntawm oxidation, hydrogen embrittlement, tshav kub tsub zuj zuj thiab ib feem tsis xws luag.

 

(II) Ua haujlwm txias

Txhawm rau kom tswj tau qhov tseeb qhov tseeb, txhim kho lub zog thiab txhim kho qhov zoo ntawm qhov chaw los ntawm kev ua haujlwm tawv, thiab hloov mus rau qhov me me - qhov loj me.

 

Cov txheej txheem thiab cov yam ntxwv

Txias dov: Refines lub thickness ntawm daim hlau nrog kev kam rau siab txog li ± 0.05mm thiab txhim kho qhov tseeb qhov tseeb.

Txias daim duab: Ua tau siab -precision titanium alloy hlau thiab tuav los ntawm kos los ntawm pwm.

Txias rotary swaging: Nta lub ntsej muag du thiab siab precision, haum rau me me -batch tshwj xeeb- zoo li tus tuav, thiab tuaj yeem kho cov nplej kom txhim kho lub zog.

 

Core tswj cov ntsiab lus

Deformation tus nqi: Ib qho - kis deformation tus nqi tsawg dua 15% los tiv thaiv cov khoom tawg.

Nruab nrab annealing: Annealing ntawm 650-700℃rau 1-2 teev yog xav tau ntawm kev ua haujlwm ntau dhau los txhawm rau tshem tawm kev ntxhov siab thiab rov ua kom zoo dua qub.

Kev tiv thaiv nto: nruj me ntsis tswj qhov saum npoo ntawm cov cuab yeej; siab- cov khoom muaj tseeb yuav tsum tau polishing tom ntej kom tsis txhob khawb.

 

Kev nyuaj

kov yeej cov yas poob los ntawm kev ua hauj lwm hardening los tiv thaiv kev tawg; tswj qhov seem thiab seem kev ntxhov siab, tshwj xeeb tshaj yog rau siab -lub zog titanium alloys, kom sib npaug zog thiab yas.

 

 

(I) Qhov txawv ntawm Microstructure

Kub ua haujlwm: Dynamic recrystallization tshwm sim ntawm qhov kub thiab txias, sib sau ua ke equiaxed nplej, tshem tawm kev ua haujlwm hardening thiab txhim kho isotropy.

Ua haujlwm txias: Tsis muaj dynamic recrystallization tshwm sim, nrog rau tsub zuj zuj ntawm dislocation ceev; Cov nplej yog elongated thiab refined, thiab qee qhov tuaj yeem tsim cov nplej nanoscale thiab nyiam kev ntxhib los mos, yog li txhim kho lub zog.

 

(II) Qhov txawv ntawm Macroscopic Properties

Mechanical zog: Kub ua hauj lwm yields zoo heev cov khoom nrog ib tug sib npaug ntawm lub zog, plasticity thiab toughness, haum rau txoj kev nyuaj siab scenarios; kev ua haujlwm txias txhim kho lub zog, hardness thiab hnav tsis kam thaum txo cov yas, haum rau siab - zog, siab -precision thiab ib zaug - kev ntxhov siab.

 

Nto zoo: Qhov saum npoo tom qab ua haujlwm kub muaj oxide txheej thiab siab roughness, yuav tsum tau kho tom ntej; Qhov saum npoo tom qab ua haujlwm txias yog dawb ntawm oxide txheej thiab tsis tshua muaj roughness nrog ib tug du tiav, tsis tas yuav tsum tau complex tom qab kho.

 

Dimensional raug: Kub ua hauj lwm yog cuam tshuam los ntawm thermal expansion thiab contraction, ua rau tsis tshua muaj neeg thiab kam rau siab loj; txias ua hauj lwm nta ib tug ruaj khov kub, siab precision thiab me me kam rau ua, haum rau zus tau tej cov precision qhov chaw.

 

 

1. Kev siv kub ua haujlwm

Aerospace: Cov qauv tis, aero- cav cav turbine disks, hniav, thiab lwm yam. Complex forming yog ua tiav los ntawm kub forging / isothermal forging kom ntseeg tau tias cov microstructure zoo ib yam thiab siab zog thiab toughness.
