Elastic constants and thermal expansion of niobium as a function of temperature
The three Independent elastic constants of the bcc niobium structure have been determined as a function of temperature over the range 4.2°-300°K, using an ultrasonic pulse technique - the propagation of 10 Me waves in preferred directions in the crystal specimen. Values obtained at 4.2°K are, in …
