Abstract:In this thesis, prepared Nb-38Ti-12Al alloy is processed into sheet. The thickness of sheet is 0. 50
mm. Based on this, X鄄ray Diffraction(XRD),optical microscope(OM),scanning electron microscope(SEM)and box re鄄
sistor鄄stove, and analytical balance are used to study the oxidation behavior of alloy. The oxidation behavior of Nb-38Ti
-12Al at 1 200益is studied. The oxidation layer appeared layering phenomenon. The calculation of oxidation weight
gain per unit area made it possible to draw oxidation weight gain curves. The kinetic equation of the intimal oxidation
layer can be expressed by x1. 228 =34. 50t and x1. 480 =288. 73t,respectively,at 1 000益and 1 200益.
