Kev kos duab ntawm titanium hlau thiab titanium alloy hlau yog cov txheej txheem hlau yas uas rub cov hlau rods lossis hlau blanks los ntawm qhov chaw ntawm daim duab tuag nyob rau hauv qhov kev txiav txim ntawm kev kos duab los tsim cov ntoo khaub lig me me -section titanium thiab titanium alloy hlau. Ntau yam duab thiab qhov ntau thiab tsawg ntawm cov hlau hlau ntawm cov hlau sib txawv thiab cov hlau sib txawv tuaj yeem tsim los ntawm kev kos duab. Cov hlau kos yog qhov loj me me, muaj qhov du, thiab cov khoom siv kos duab thiab cov pwm siv tau yooj yim thiab yooj yim los tsim. Thaum kos duab ultra- cov xov hlau zoo nrog txoj kab uas hla tsawg dua 0.05mm, nws tuaj yeem nyuaj dhau los ntawm kev tuag; txhawm rau txhim kho kev ruaj ntseg ntawm cov txheej txheem kev kos duab, txo tus naj npawb ntawm kev tawg thiab tuag dhau, thiab txhim kho kev tsim cov duab kos, qhov kev nyab xeeb ntawm K tus nqi ntau dua 2.0 tuaj yeem txais yuav.
Kev kos duab kub yog cov txheej txheem kos duab saum toj no qhov ntsuas kub ntawm recrystallization, thaum lub teeb sov sov tshwm sim ntawm qhov kub siab tshaj hauv chav sov tab sis qis dua qhov kub ntawm recrystallization. Kev kos duab txias yog txoj kev siv ntau tshaj plaws hauv kev tsim cov hlau thiab cov hlua. Thaum lub sij hawm kub kub, cov hlau hlau yuav tsum tau rhuab ua ntej nkag mus rau hauv lub qhov tuag, feem ntau yog siv los kos cov hlau melting point zoo li tungsten thiab molybdenum. Hauv kev kos duab sov, cov hlau hlau kuj yuav tsum tau muab cua sov rau qhov kub thiab txias ua ntej nkag mus rau hauv qhov tuag rau kev kos duab, feem ntau yog siv los kos cov zinc hlau thiab nyuaj - rau -deform alloy hlau xws li siab - steel hlau thiab bearing steel.
