Kev npaj ntawm Aluminium Foam nrog Uniform Distribution of Me Pore Size los ntawm Novel Composite Foaming Agent

Cov hlau foamed, tshwj xeeb tshaj yogaluminium ua npuas ncauj, yog nce dav siv nyob rau hauv cov ntaub ntawv teb. Cov txheej txheem yaj foaming tau siv dav hauv kev tsim khoom vim nws qhov kev npaj siab ua haujlwm thiab cov khoom lag luam ruaj khov. Txawm hais tias qhov kev sib raug zoo ntawm cov khoom thiab cov qauv pore tseem tsis tau nkag siab tag nrho, cov foams faib ua ke nrog cov pore me me thiab qhov tsis xws luag yog ib txwm xav tau.

Tam sim no, qhov pore loj thiab cov qauv ntawmaluminium foamsNws yog ib qho nyuaj rau tswj thaum lub sij hawm yaj foaming txheej txheem, thiab nws yog ib qho nyuaj rau fabricate aluminium foams nrog me me pore qhov ntau thiab tsawg, feem ntau yog vim thaum ntxov decomposition thiab tsis zoo dispersion ntawm lub tshuab tshuab (feem ntau TiH2). Raws li qhov no, pab pawg ntawm Prof. Yanxiang Li ntawm Tsinghua University tau kawm txog cov txheej txheem ntawm pre-dispersion ntawm TiH2 nyob rau hauv lub yaj ntawm AlMg35 intermediate alloy tom qab oxidation kev kho mob, uas yuav ua kom tiav cov dispersion txheej txheem tsis decomposition, thiab tsim ib tug tshiab AlMg35-TiH2. composite foaming tus neeg sawv cev. Cov teebmeem ntawm stirring lub sij hawm thiab tshuab tus neeg saib xyuas ntau npaum li cas ntawm qhov zoo ntawm cov txhuas ua npuas ncauj kuj tau soj ntsuam. Cov txiaj ntsig kev tshawb fawb tau luam tawm nyob rau hauv phau ntawv journal "Journal of Materials Processing Technology" nrog lub npe "Kev Tsim Kho ntawm AlMg35-TiH2 composite foaming agent thiab fabrication of me pore size aluminium foams". Phau ntawv Journal of Materials Processing Technology.Aluminium foamsnpaj nrog tus neeg sawv cev ua npuas dej sib xyaw no yog cov qauv zoo, qhov pore me me, cov pore faib thiab spherical pore zoo. Qhov kev txhim kho ntawm cov txheej txheem no yog tias TiH2 hais tau tawg mus rau hauv qhov qis melting point alloy yaj los ntawm lub sij hawm stirring ntev dua thiab tsis yooj yim rau decompose.

Tus neeg sawv cev tshuab tau ua tiav hauv kev npaj cov txheej txheem cellular zoo thiab rov tsim dua tshiab ntawm cov pores me me hauv aluminium foams nrog txo qhov nruab nrab qhov pore loj ntawm 0.6 hli, uas yog vim li cas rau lub sij hawm qeeb decomposition ntawm TiH2 vim kev kho ua ntej oxidation thiab AlMg35 embedded nyob rau hauv nws. , uas ua rau lub sij hawm stirring ntau tolerable. Cov khoom ua ntej oxidized TiH2 tau tawg nyob rau hauv cov kua AlMg35 alloy, ua kom yooj yim rau disperse TiH2 hais nyob rau hauv lub txhuas yaj nrog tsawg particle aggregation. Tsis tas li ntawd, txoj kev txo cov nqi ntawm TiH2 ntxiv nyob rau theem foaming, uas yog tsawg dua thiab tsim nyog rauindustrial manufacturing.
