A6061 Hmoov Metallurgy Pressed Parts
Aluminium matrix composites yog heterogeneous sib tov raws li txhuas thiab nws cov alloys, ntxiv dag zog los ntawm hlau, non-metallic hais, whiskers, los yog fibers, thiab yog dav siv nyob rau hauv aerospace, automotive, thiab lwm yam teb. Txij li thaum lub reinforcement tuaj yeem muab ntxiv rau cov khoom sib xyaw matrix hauv txhua qhov kev faib ua feem los ntawm kev siv txoj kev, qhov kev txhawb nqa kuj yog ib qho yooj yim los tsim ib qho kev faib tawm ntau dua ntawm cov nplai macroscopic, qhov kub ntawm sintering yog tsawg, thiab cov tshuaj tiv thaiv interface yog yooj yim los tswj.

Aluminium matrix composites yog heterogeneous sib tov raws li txhuas thiab nws cov alloys, ntxiv dag zog los ntawm hlau, non-metallic hais, whiskers, los yog fibers, thiab yog dav siv nyob rau hauv aerospace, automotive, thiab lwm yam teb. Txij li thaum lub reinforcement tuaj yeem muab ntxiv rau hauv cov khoom sib xyaw matrix hauv txhua qhov kev faib ua feem los ntawm kev siv txoj kev, qhov kev txhawb nqa kuj yog ib qho yooj yim los tsim ib qho kev faib tawm ntau dua ntawm cov nplai macroscopic, qhov kub ntawm sintering tsawg, thiab cov tshuaj tiv thaiv interface yog yooj yim los tswj; Nyob rau tib lub sijhawm, kev ua tau zoo thiab kev ruaj ntseg ntawm cov khoom siv tau zoo dua li cov uas tau npaj los ntawm lwm txoj kev, yog li cov hmoov hlau metallurgy txoj kev tau dhau los ua cov txheej txheem feem ntau siv rau kev npaj ntawm aluminium matrix composites.
Cov txheej txheem rau kev npaj cov khoom sib xyaw los ntawm hmoov metallurgy
1. Sib tov hmoov
Cov kev sib xyaw dav dav suav nrog kev sib xyaw qhuav zoo tib yam, pob milling, thiab sib xyaw ntub dej. Ntawm peb txoj kev sib xyaw hmoov, kev sib xyaw qhuav zoo tib yam thiab sib xyaw ntub dej yog qhov ua rau tsis sib xws ntawm cov khoom siv ntxiv thiab ntau cov agglomeration thiab txheej txheej. Pob milling feem ntau yog siv ntau dua thiab siv tau zoo.
2. hmoov ua ntej nias
Tom qab cov hmoov sib tov ua tiav, cov hmoov pre-pressing kho yog nqa tawm. Hmoov pre-pressing txoj kev mas muaj xws li txias nias thiab txias isostatic nias. Nyob rau hauv sib piv, txias nias yog ib qho kev lag luam thiab feem ntau siv hmoov pre-pressing txoj kev. Tom qab cov hmoov txhuas txhuas yog pre-pressed, qhov pre-compact ntom feem ntau yuav tsum yog 70 feem pua rau 80 feem pua ntawm cov khoom sib xyaw kom haum rau kev khiav tawm ntawm cov pa thaum lub sij hawm degassing. Txij li cov hmoov txhuas thiab cov khoom txhawb nqa tau yooj yim nqus dej vapor thiab oxidize, cov hmoov ntsuab lub cev yuav tso tawm ntau cov dej vapor, hydrogen, carbon dioxide, thiab carbon monoxide thaum cua sov. Yog li ntawd, lub cev ntsuab yuav tsum tau degassed ua ntej kub ua kom tsis txhob muaj cua npuas thiab tawg ntawm cov khoom; qhov degassing kub yuav tsum feem ntau sib npaug los yog me ntsis siab dua qhov kub nias tom ntej, kub ua deformation, thiab kub kho kub kom tsis txhob npuas thiab delamination nyob rau hauv cov khoom tshwm sim los ntawm residual dej thiab roj nyob rau hauv lub compact. Txawm li cas los xij, yog tias qhov kub thiab txias dhau lawm, qee qhov lwm cov ntsiab lus hauv aluminium alloy yuav raug hlawv, thiab cov khoom sib txuas intermetallic uas ua lub luag haujlwm ntxiv dag zog rau cov hlau yuav sib sau ua ke thiab coarsen, txo cov kev ua haujlwm ntawm cov khoom.
3. Kev kho
Tom qab cov hmoov tau degassed, nws yog densified, piv txwv li sintered, kub pressed, kub isostatically nias, thiab kub pressed xoob hmoov los yog pre-pressed hmoov. Nyob rau hauv cov ntaub ntawv ntawm kom ntseeg tau tias tsis tshua muaj nqi thiab siab productivity, lub billet yog tsim los ntawm uniaxial txias extrusion, tom qab degassing, nws yog tsa mus rau ib tug tej yam kub ntawm ib tug tej yam nqi, thiab kub extruded raws li ib tug tej yam extrusion piv, thiab ces qhov kawg kub. kev kho mob yog nqa tawm kom tau txais cov khoom kawg. Cov txheej txheem hmoov no ua ke nrog cov hmoov metallurgy nrog cov kev kho mob densification (xws li extrusion, dov, thiab lwm yam) ua rau cov hmoov mus rau cov yas deformation nyob rau hauv lub sij hawm luv luv kub thiab siab siab thiab tom qab ntawd paub txog kev sib txuas ntawm cov hmoov hmoov. Piv nrog rau cov pa hmoov metallurgy txoj kev, ntxiv rau peb-dimensional compressive kev nyuaj siab, cov hmoov hais kuj dais ib tug loj shear quab yuam raws lub extrusion kev taw qhia thaum lub sij hawm extrusion txheej txheem. Lub zog ntawm daim ntawv cog lus ntawm cov hmoov uas nyob ib sab yog ntxiv txhim kho tom qab cov oxide zaj duab xis ntawm qhov chaw tawg. Piv nrog rau tus nqi siab kub isostatic nias txheej txheem, cov txheej txheem tshwj xeeb ntawm kev npaj cov ntaub ntawv sib xyaw los ntawm cov hmoov hlau metallurgy suav nrog cov kauj ruam hauv qab no.
