Effects of Alloy Elements (Mo, Al, and B) Addition on the Damping Property of Ti-25Nb-1.5O Alloys

Abstract:

The influence of addition elements Mo, Al and B on the Snoek damping behaviors of Ti-25Nb-1.5O were investigated, the alloys were prepared in a vacuum induction electric arc furnace. By means of X-ray diffraction, scanning electron microscopy and dynamic mechanics analyzer, it was found that Mo or Al element addition is unfavorable for the damping properties of the alloys, but Mo element addition improved the dynamic storage modulus. A few B elements addition can improve the damping capacity and the damping stability after the thermal cycle simultaneously. In addition, a large number of B elements additions can dramatically improve the dynamic storage modulus.
