Txheeb xyuas seb dab tsi yog qhov tseem ceeb cuam tshuam rau kev sib zog ua haujlwm ntawm cov pas nrig titanium
Titanium pas nrig zoo ib yam li lwm cov hlau. Nws tus cwj pwm kev nqaim thaum lub sij hawm pov tseg kuj tseem hloov pauv los ntawm cov kua mus rau lub xeev khov thiab tom qab ntawd mus rau lub xeev ruaj khov. Qhov kev coj tus cwj pwm no feem ntau muab faib ua qhov ntim me me thiab nqaim nqaim. Kev cog lus ntawm lub cev
Xav txog qhov kev hloov pauv hauv tag nrho ntim ntawm cov khoom thaum txheej txheem txheej txheem. Txij li thaum tag nrho cov ntim shrinkage yog sib npaug rau qhov ntim ntawm qhov sib zog ua kom muaj kab noj hniav ntawm cov casting ntxiv rau qhov ntim ntawm qhov ntsws ntsws, qhov ua kom sib zog ua rau me me tus cwj pwm ntawm cov txheej txheem txheej txheem hlau cuam tshuam nrog rau qhov ntim me me ntawm cov hlau, uas txiav txim siab qhov drilling cov yam ntxwv ntawm cov kab noj hniav me me thiab shrinkage porosity tsis xws luag ntawm cov hlau yog qhov tseem ceeb heev rau kev nkag siab txog kev tsim cov kab noj hniav me me thiab shrinkage porosity tsis xws luag hauv cov khoom.
Yam tseem ceeb cuam tshuam rau kev ua kom khov thiab ua kom qis ntawm cov pas nrig titanium suav nrog cov khoom sib xyaw, cov khoom siv pwm thiab cov qauv pwm. Vim tias cov ntsiab lus sib xyaw ua rau cuam tshuam rau qhov sov ua kom sov sib nrug ntawm cov khoom, ib yam li nws cov txiaj ntsig ntawm cov kua dej, qhov sib zog ua kom sib zog ntawm titanium pas nrig ua ntej yog nyob ntawm tus yam ntxwv ntawm cov khoom sib xyaw ntxiv, uas yog, qhov sov ua kom sov tsim los ntawm titanium thiab cov khoom sib xyaw ntawm lub caij nyoog muaj feem cuam tshuam. Eutectic titanium raj nrog nqaim crystallization kub sib nrug muaj qhov ua tau zoo thiab yooj yim los tsim cov lus sib zog ua kom cov kab noj hniav, thaum titanium pas nrig nrog dav crystallization kub sib nrug muaj cov dej tsis zoo thiab yooj yim rau tsim cov kab sib cais shrinkage, uas yog, shrinkage porosity.
