Rau cov kws tsim hluav taws xob tsim cov ntaub thaiv hluav taws xob rau aero- cav, siab - lub siab li qub, lossis cov khoom siv sab hauv ntawm cov tshuab hluav taws xob, qhov kev sib tw loj nyob hauv qhov tsis sib xws ntawm lawv cov coefficients ntawm thermal expansion. Thaum cov khoom sib txawv nthuav dav ntawm tus nqi sib txawv thaum lub sij hawm cua sov ceev (txog 700 degree), cov teeb meem hauv qab no tuaj yeem tshwm sim:
Kev qaug dab peg:Cov khoom txav txav tuaj yeem txeeb tau vim qhov kev nthuav dav tsis txaus ntseeg.
Poob ntawm cov qauv kev ncaj ncees:Cov kev ntxhov siab sab hauv siab heev tuaj yeem ua rau hauv zos buckling lossis "warping."
Fatigue cracking:Rov ua dua thermal cycling tuaj yeem ua rau pob txha tawg ntxov ntxov.
Nkag siab txog cov khoom ntawmGH4169 daim hlauNws yog ib qho tseem ceeb kom kov yeej cov teeb meem no.hwv 4169(piv rau hauv kev ua tau zoo rauib 718) yog txaus siab rau nws qhov sib npaug coefficient ntawm kev nthuav dav thiab siab thermal stability, ua kom cov qauv kev ruaj ntseg thiab xoom deformation txawm nyob rau hauv qhov kev xav tau siab tshaj - qhov kub thiab txias.
