Abstract
The thermal expansion and Young’s modulus of the cobalt and palladium alloys have been measured in the temperature range from 0° to 990°C with a dilatometer and by means of a vibrator-controlled oscillator system, respectively, and it has been found that the mean linear thermal expansion coefficient (0°∼40°C) shows maximum value in the α phase alloy containing 90%Pd which has a ferromagnetic Curie point of 150°C and the mean temperature coefficient of Young’s modulus (0°∼40°C) shows a positive value in the concentration range of 90.5∼95%Pd, and its largest positive value is +59.78×10−5 in the alloy containing 94% palladium.
