Comparison of the Temperature-Dependent Elastic Modulus of Ti-Fe with H-Doped Ti-Fe in the (111) Direction.

Abstract

The velocity of sound has been measured as a function of temperature between 4 and 300 K in the intermetallic compound TiFe and in H-doped TiFe. The data were taken in the (111) direction and yield a modulus of 2.64 x 10 to the plus 12 dyne/centimeters squared for that direction at room temperature in pure TiFe. Addition of H (approximately 0.4 at.%) increases the room temperature modulus by 0.9%. By using estimates of the thermal expansion the moduli have been obtained as a function of temperature and at low temperatures show a decrease with H addition - in contrast to the room-temperature behavior.
