The thermal expansion and Young’s modulus of the cobalt and palladium alloys have heen measured in the temperature range from 0° to 990°C with a dilatometer and by means of an electrostatic vibrator-controlled oscillator system, respectively. It has been found that the mean linear coefficient of thermal expansion (0°∼40°C) shows a 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 composition range of 90.5∼95% Pd, its largest positive value being +59.78×10−5 in the alloy containing 94% palladium.
