Linear Thermal Expansion Coefficient of Nickel NP2 Brand

The results of an experimental study of thermal expansion of the polycrystalline nickel NP2 brand in the temperature range 293.15–1400 K are presented. An anomaly of the linear thermal expansion coefficient in the temperature region of 500–700 K are observed. The effect of the purity of the metal on...

Description
Summary:The results of an experimental study of thermal expansion of the polycrystalline nickel NP2 brand in the temperature range 293.15–1400 K are presented. An anomaly of the linear thermal expansion coefficient in the temperature region of 500–700 K are observed. The effect of the purity of the metal on the temperature of the phase transition of the second kind is confirmed. The temperature dependences of volumetric properties of nickel NP2 brand are determined.
