Ib qho - dhau cov khoom siv ntau - txheej tso cov khoom tso tawm tauricated los ntawm arc adcessitive tsim cov kab ke hauv kev hloov pauv hlau txias. Tom qab teeb tsa cov txheej txheem tsis muaj, ntau yam cuab yeej siv tau siv los ntsuas cov khoom siv hluav taws xob, thiab lwm yam los sim ua rau kev tsim hluav taws xob thermal ntawm arc.
Hais txog microstructure, cov khoom siv yog tsim ntawm kev nplua equiaxed nplej. IHT muaj cov nyhuv me me rau lub noob nplej loj, tab sis solution atom doltaries rau dnases rau hauv matrix thiab hloov mus rau theem s - al₂cumg theem. Cov nplua zoo η - mg (zn (Zn, Cu, al) ₂ theem nqus solution atoms thiab loj tuaj thiab ua ib qho chaw nag lossis nag dawb. Sab hauv nplej, nrog kev nce hauv ITHT lub sijhawm ua, kev laus kev hloov pauv, thiab thaum kawg, η theem hloov, thiab T theem zuj zus.
Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab, txo hauv cov tshuab tshuab yog vim yog kev hloov pauv ntawm grololution - ciam teb precipitates. Cov kev hloov pauv hauv grain - ciam teb ua ntej txo cov plastentic ntawm cov khoom, thiab nag los ua kom muaj txiaj ntsig zoo, ua rau muaj kev txo qis hauv lub zog.
Saib ntawm thaj tsam sib txawv ntawm cov khoom sib txawv ntawm cov khoom siv, cov kws kho tshuab hauv thaj av sab saum toj yog qhov zoo tshaj plaws, thiab los ntawm sab saum toj mus rau hauv qab thaj tsam maj mam txo qis. Los ntawm kev kawm cov kev hloov pauv ntawm microstructure ntawm micrertory thiab cov neeg ua haujlwm nyob rau hauv IHT thaum lub ARC Admucture Manufacturing kev tsim khoom, peb qhia meej txog kev hloov pauv ntawm cov txheej txheem no. Qhov no tsis tsuas yog muab cov txheej txheem tsim nyog rau cov arc adjitive manufacturing kev ua kom zoo dua kev txhim kho kev ua tau zoo ntawm Tic / TN - FU Alloy Cheebtsam.
Nyob rau hauv kev tshawb fawb yav tom ntej, nws yog ib qho tsim nyog los tshawb xyuas qhov kev sib cuam tshuam ntawm IHT thiab txhawb nqa cov txheej txheem dav dav ntawm arc ntxiv kev tsim khoom siv thev naus laus zis hauv cov teb no.
