چکیده
Titanium and titanium alloys have excellent physical properties process are widely used in the aviation industry, but their high-temperature oxidation resistance is poor, there a thermal barrier temperature of 600 °C, which limits application as components. The Self-generated Gradient Hot-dipping Infiltration (SGHDI) method to prepare Ti-Al-Si gradient coating based on silicon concentration with compact Ti(Al,Si)3 phase layer, can effectively improve alloy. Adding cerium inhibit generation τ2: Ti(AlxSi1−x)2 within certain hot infiltration time so form continuous dense Al2O3 layer further coating. Studies found that multiple Ti-Al binary alloy layers formed during process, has effect isolating oxygen crack growth, improving performance.

Effects of a high-gradient magnetic field on the migratory behavior of primary crystal silicon in hypereutectic Al-Si alloy.
The migration of primary Si grains during the solidification of Al-18 wt%Si alloy under a high-gradient magnetic field has been investigated experimentally. It was found that under a gradient magnetic field, the primary Si grains migrated toward one end of the specimen, forming a Si-rich layer, and the thickness of the Si-rich layer increased with increasing magnetic flux density. No movement o...

متن کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Gradient Distribution of Martensite Phase in Melt-Spun Ribbons of a Fe-Ni-Ti-Al Alloy
Metallographic, X-ray diffraction and magnetometric analysis were used to study the regularities of martensitic transformation in melt-spun ribbons of a Fe - 28 wt. % Ni - 2.1 wt. % Ti - 2 wt. % Al - 0.05 wt. % C alloy. The substantial differences in volume fractions of the martensite phase in local regions of thin melt-spun ribbons of the alloy are related to the size effect of the transformat...
