3D Printing Nitinol Qwsyog ib qho ntawm cov khoom ntawm nitinol nco alloy. Nickel-titanium nco alloy ua rau 3D luam ntawv hlau cov ntaub ntawv tiv taus kub kub los ntawm kev kho cua sov tshiab.
Txawm hais tias 3D luam ntawv thev naus laus zis tuaj yeem tsim cov khoom siv hlau zoo, cov khoom siv hlau luam tawm feem ntau deformed los ntawm kev quab yuam thiab cua sov thiab muaj qhov teeb meem ntawm qhov tsis muaj zog. Vim li no, kev kho cua sov thev naus laus zis tsim los ntawm Massachusetts Institute of Technology yuav ua rau qhov xwm txheej no tsis tshwm sim ntxiv lawm.
Qhov kev sib tw rau kev ua haujlwm ntev ntawm cov khoom siv hlau 3D uas twb muaj lawm yog qhov tshwm sim hu ua "creep", uas cov khoom siv deform maj mam thiab mus tas li nyob rau hauv kev ntxhov siab thiab kub siab, tshwj xeeb tshaj yog nyob rau hauv 3D luam ntawv, qhov twg cov ntaub ntawv hlau yog ua los ntawm cov hmoov nplej zoo. yooj yim rau creep phenomenon.
Yog li ntawd, pab pawg MIT tau tsim cov txheej txheem recrystallization kev kho cua sov kom ua kom cov nplej loj dua thiab tsis tshua nkag mus.
Hauv kev sim kuaj, 3D-luam nickel alloy pas nrig yuav muab tso rau hauv chav dej kub da dej ncaj qha hauv qab induction kauj, thiab tom qab ntawd maj mam dhau los ntawm cov kauj ntsug ntawm qhov sib txawv, maj mam cua sov txhua feem ntawm cov nickel alloy pas nrig rau 1,200. C ~ 1,245 C, tsim kom muaj cua sov gradient ntawm cov hlau sab hauv, lub kauj, thiab dej.
Qhov gradient no hloov cov hlau microscopic nplej rau hauv cov nplej "columnar" loj dua. Nyob rau hauv cov nqe lus ntawm cov khoom siv, qhov zoo tshaj plaws kub poob ntawm 1,235 C thiab ib tug ceev ntawm 2.5 centimeters ib teev, nyob ntawm seb lub hom phiaj ntawm 3D luam ib feem, cov grain qauv ntawm ib tug neeg cov khoom yuav hloov tau los ntawm kev hloov kub thiab ceev thaum lub sij hawm. ua.
Tam sim no, pab neeg no tseem npaj yuav sim cov thev naus laus zis tshiab zoo ib yam li roj turbine lossis dav hlau cav hniav. Cov khoom no yuav tsum tiv taus kev ntxhov siab tsis tu ncua thiab kub siab. , ntau npaum 3D luam ntawv tsim, 3D luam ntawv nitinol rods yuav siv tau.
