Measurements on the ultrasonic attenuation and velocity are presented for several Invar-type iron-nickel alloys in the temperature range 1·5-77°K. The results are interpreted in terms of the presence of a relaxation mechanism within the alloys, and a simple relation is derived between the attenuation and the rate of change of the elastic modulus with temperature.
