Aluminium tau dhau los ua cov khoom siv dav hauv ntau yam lag luam vim nwsmuaj zog heevthiab tiv taus xeb zoo heev. Txawm li cas los xij, cov khoom ntuj tsim ntawm txhuas muaj qee qhov kev txwv, tshwj xeeb tshaj yog hais txog qhov zoo ntawm qhov chaw. Txhawm rau kov yeej cov kev txwv no, kev ua kom zoo ntawm cov noob ntawm txhuas thiab cov hlau txhuas yog qhov tseem ceeb heev.
Kev ua kom cov noob ntoo zoo yog ib qho txheej txheem uas txo qhov loj ntawm cov noob ntoo hauv cov khoom siv microstructure, ua rau nws sib xws thiab ntom dua. Cov txheej txheem no yog qhov tseem ceeb los txhim kho lub zog, plasticity thiab tag nrho cov khoom siv kho tshuab ntawm cov khoom siv txhuas lossis castings. Qhov zoo ntawm qhov chaw ntawm cov profiles kuj tau txhim kho, ua rau muaj qhov zoo sib xws, ci ntsa iab.
Yuav kom ua tiav qhov kev ua kom cov noob no zoo, feem ntau siv hauv kev ua lag luam yogAl-Ti-B boron hlau additiveCov hlau ntxiv yog 9.5 hli hauv txoj kab uas hla, hnyav kwv yees li 100 kg (170 kg) ib yob, thiab muaj 5% titanium (T) thiab 1% boron (B). Nws yog tsim los ua kom tau raws li qhov xav tau ntawm cov khoom siv txhuas thiab cov hlau txhuas.
Al-Ti-B boron hlau Additive muaj ntau yam txiaj ntsig, ua rau nws yog qhov kev xaiv zoo heev rau txhua txoj kev ua kom huv. Ua ntej, nws txhim kho cov khoom ntawm cov khoom siv txhuas lossis castings. Lub zog thiab plasticity ntawm cov khoom tau txhim kho, ua rau nws haum rau cov ntawv thov uas xav tau cov khoom siv kho tshuab siab.
Tsis tas li ntawd xwb, cov hlau no txo cov nqi pov tseg, ua rau txuag tau nyiaj thiab ua rau muaj kev tsim khoom ntau dua. Los ntawm kev txhim kho qhov zoo ntawm qhov chaw, ua kom cov profiles muaj qhov zoo sib xws, ci ntsa iabthiabntxiv tus nqi zoo nkauj rau cov khoom kawg.
Ib qho txiaj ntsig tseem ceeb ntawm Al-Ti-B Boron hlau additive yog nwstxoj kev ntawmsiv. Nws tau siv sab nraumlub cub tawg, thaum cov dej txhuas raug tso tawm, ncaj qha ntxig rau hauv txhuas titanium boron hlau mus rau hauvlub tshuab ntxhua khaub ncaws ceramic los ntawm lub feeder kom yaj thiab ua kom zoo, thiab xyuas kom meej tias cov hlau txhuas titanium boron thiab cov kua txhuas sib cuag tau ntau dua 1 feeb (zoo dua 2-10 feeb). Feem ntau, cov tshuaj yog 0.8-1.3kg / ton ntawm txhuas (lub cheeb ntawm cov hlau txhuas-titanium-boron yog 9.5 hli, thiab qhov hnyav yog 0.192kg / m). Ntxiv mus, cov khoom ntxiv ua kom ntseeg tau tias titanium boron tsis ploj thaum lub sijhawm ua kom zoo.
Qhov ua tau ntau yam ntawm cov hlau ntxiv no ua rau nws haum rau ntau yam kev siv. Siv dav hauv kev ua cov txhuas castings, txhuas profiles, txhuas cables, txhuas ntawv ci thiab lwm yam lag luam.
