Kev Siv Aluminium Titanium Boron Alloy

Tus qauv zoo tagnrho ingot yog cov niaj hnub zoo thiab zoo nkauj equiaxed muaju rau ntawm txhua qhov hla ntu ntawm ingot. Vim tias cov kab hluav taws xob equiaxed yog me me hauv anisotropy, lawv zoo li tsis zoo thaum lub sijhawm ua haujlwm, muaj cov khoom zoo nkauj yas, thiab muaj cov khoom zoo heev, uas zoo rau kev nrum thiab cov yas ua tom ntej. Yuav kom tau txais cov qauv no, cov yaj yog feem ntau ua kom zoo hauv kev tsim khoom. Cov txheej txheem nquag siv ntawm kev txhim kho nplej yog siv cov lis nplej rau kev hloov pauv. Metamorphism yog ib txoj hauv kev ntxiv ib qho me me ntawm cov khoom siv nquag mus rau lub hlau nchuav ua kom txhawb sab hauv nucleation ntawm cov kua hlau lossis hloov cov txheej txheem loj hlob siv lead ua. Tam sim no qhov feem ntau siv hauv Suav teb yog qhov hloov kho nucleation. Tus txheej txheem ntawm kev hloov kho ntawm nucleation yog ntxiv ib co tshuaj uas tuaj yeem tsim cov tsis muaj kuab rau cov txhuas yaj, kom nws tuaj yeem ua tiav tiav los ntawm heterogeneous nucleation thaum solidification. Lub hom phiaj ntawm crystallizing
