Taw qhia rau austenite grain
Austenite yog ib qho kev sib xyaw ua ke ntawm cov pa roj carbon nyob rau hauv γ-Fe thiab muaj lub ntsej muag-nruab nrab ntawm lub cubic qauv. Vim tias qhov kev txwv ntawm lub ntim qhov ua haujlwm (qhov hluav taws xob ntawm cov pa roj carbon atoms yog 0.077nm, thiab qhov sib txawv ntau tshaj plaws ntawm crystal-Fe cov qauv siv lead ua, uas yog, octahedral gap radius yog 0.053nm), qhov siab tshaj plaws khoom solubility ntawm carbon hauv γ -Fe tsuas yog 2.11% (feem seem loj).
