Abstract
A pulse-echo technique utilizing a wave guide operating at high temperatures has been used to measure the variation in the Young’s modulus and shear modulus of pure platinum, nickel, and molybdenum in the temperature range from 25 to 1000°. With the exception of Ni in the temperature range below the Curie point, linear behavior was found for all three metals. The significance of the linear relation between temperature and the elastic constants for Mo to the observed nonlinearity of the Arrhenius plot of the diffusivity of carbon in Mo is discussed.
