Khoom nta thiab kev siv
Cov yam ntxwv ntawm Ti75 Alloy Phaj.
Lub transverse tensile lub zog, tawm los lub zog, elongation, thiab tej yam toughness ntawm Ti75 alloy daim ntawv yog superior rau cov nyob rau hauv lub dov kev taw qhia, tshwj xeeb tshaj yog nrog ib tug loj sib txawv nyob rau hauv yield zog, uas ua rau ib tug ntau dua transverse yield piv tshaj nyob rau hauv lub dov kev taw qhia, thiab daim ntawv qhia anisotropy tseem ceeb.
Daim ntawv thov teb
Ti75 Alloy Phaj sib xyaw ua ke qhov zoo ntawm ntau yam titanium alloys, nrog rau cov yam ntxwv xws li lub zog nruab nrab, siab toughness, thiab zoo weldability. Nws tau tsim los ua kom tau raws li qhov xav tau ntawm lub nkoj fais fab tshuab thiab nkoj tshuab, thiab nws qhov kev ua tau zoo yog piv rau cov nkoj Lavxias titanium alloy π T-3B. Nws tau siv rau hauv reciprocating dej ntsev twj, dej hiav txwv systems, pob valve stems, thiab lwm yam khoom, thiab muaj broad daim ntawv thov kev cia siab nyob rau hauv lub teb ntawm ships, roj av, tshuaj engineering, thiab lwm yam. Nyob rau hauv lub teb ntawm ships, titanium alloy cov ntaub ntawv yog feem ntau siv raws li cov kav dej, tshwj xeeb tshaj yog nyob rau hauv high-pressure, ceev txaus, thiab nruab nrab cov kav dej muaj txiaj ntsig zoo dua, thiab cov kav dej muaj txiaj ntsig zoo. kev ntseeg siab ntawm cov kav dej.
Cov khoom lag luam nthuav dav tsom xam
Lub anisotropy ntawm yield zog thiab cuam tshuam toughness ntawm Ti75 Alloy Phaj feem ntau yog tshwm sim los ntawm kev ntxhib los mos ntawm daim ntawv, thaum lub zog tensile feem ntau nyob ntawm lub zog ntawm cov ntsiab lus. Qhov sib txawv influencing yam ua rau muaj qhov sib txawv tseem ceeb nyob rau hauv lub tensile yield ratio ntawm daim ntawv nyob rau hauv sib txawv cov lus qhia.
Qhov cuam tshuam toughness ntawm Ti75 alloy daim ntawv yog ze ze rau kev laus kub thiab lub sijhawm laus. Thaum tsim cov txheej txheem kev laus, kev saib xyuas yuav tsum tau them rau ob qho tib si lub sijhawm laus thiab kev laus kub. Xav txog kev siv lub zog ntawm kev kho cua sov, 750℃/ 2h / AC aging txheej txheem tuaj yeem siv los txhim kho qhov cuam tshuam toughness ntawm Ti75 alloy nrog txheej txheej.
