Q8: Cov qauv me me sib txawv li cas ntawm cov hlau sintered thiab cov hlau yaj?

Cov qauv me me sib txawv li cas ntawm cov hlau sintered thiab cov hlau yaj?

Cov hlau sintered muaj cov hmoov sib txuas nrog cov ciam teb ntawm cov khoom me me uas tswj tau

thiab porosity xaiv tau. Lawv cov microstructure tuaj yeem tsim kho kom ua tiav cov dej ntws tshwj xeeb,

kev lim dej, lossis cov khoom siv kho tshuab.

Cov hlau yaj khov los ntawm cov kua thiab feem ntau tsim cov noob loj dua nrog cov qauv txuas ntxiv mus.

Txawm hais tias qhov no tuaj yeem muab lub zog zoo heev, nws tsis muaj qhov yooj ywm microstructural ntawm hmoov metallurgy.

Qhov sib txawv tseem ceeb no piav qhia vim li cashmoov metallurgy vs kev yaj ib txwm muajua rau

cov khoom siv ua tau zoo thiab cov ntawv thov sib txawv.
