Thermal Expansion and Temperature Dependence of Young’s Modulus of Nickel-Copper Alloys

抄録

The thermal expansion coefficient and the temperature coefficient of Young’s modulus in nickel-copper alloys have been determined with a vertical dilatometer previously designed by one of the present authors and by means of a vibrator-controlled oscillator system, respectively. And it has been found that the mean linear coefficient of thermal expansion (0°∼40°C) vs. composition curve against the composition axis is convex in the ferromagnetic region and concave in the paramagnetic region and also the mean temperature coefficient (0°∼40°C) of Young’s modulus shows negative values in the whole composition range of the alloys except the maximum value of +2.1×10⁻⁵ in the alloy containing 29.85% Cu.
