Dynamic Recrystallization Ntawm Titanium Aloy Ti-6Al-4V Thaum Thermal Deformation

Dynamic recrystallization ntawm titanium alloy Ti-6Al-4V thaum lub sij hawm thermal deformation

Titanium alloy ti-63al-4v yog dav siv nyob rau hauv thaj chaw ntawm aerospace, uas muaj cov thermal conductivity thiab tsawg elastic modulus.Tshos tib lub sij hawm, nws kuj yog ib hom nyuaj rau cov khoom uas tsis zoo, cov txheej txheem ntawm machining, lub siab kub thiab siab siab ua los ntawm cov kab ntiv taw-chip hu ua accelerates cov coj ntawm lub cuab tam, titanium keeb yog ib qho yooj yim rau hnov mob nrog ntau yam kev sib raug zoo thiab cov ntsiab lus nyob rau hauv lub cuab tam, thiab cov yas deformation yuav ua rau ntau dua kev co ntawm lub cuab tam thiab cov workpiece.Nws tam sim no, tus qauv tseem ceeb los daws qhov kev tsis txaus siab ntawm cov ntaub ntawv thoob cov titanium alloy thiab cov teeb meem hauv machining yog kev kub ceev.Yog li, txoj kev tshawb ntawm thermal deformation txoj cai thiab cov khoom ntawm titanium alloy ti-6al-4v nyob rau hauv siab kub thiab siab cheeb tsam tau ua ib qho kev tshawb nrhiav hotspot.

Dynamic recrystallization yog ib qho kev hloov ntawm cov ntshiab hlau, cov hlau alloy, alloy compounds thiab non-metallic cov ntaub ntawv nyob rau hauv kev kub thiab siab.Titanium alloy ti-6al-4v yuav ua rau dynamic recrystallization hauv siab thiab siab, thiab cov kev nyuab siab softening nyhuv yog pom tseeb
