Density of copper-aluminum alloys at temperatures up to $1400^\circ$C determined by the gamma-ray technique
Annotation
The absolute method of penetrating gamma radiation has been used to measure temperature dependence of density for the $\mathrm{Cu}$–$\mathrm{Al}$ alloys, which contain $0$ to $100$ at % of one of the components, in the temperature range between room temperature and $1300$–$1400^\circ$C. Based on the experimental values of density, the parameters of the linear approximation of its temperature dependence have been calculated. These parameters have been used then to calculate values of density at certain values of temperature and to plot density isotherms. Density jumps at melting for the specimens have also been determined.
