摘要:
A role of equilibrium of condensed phases with gas in some types of heat treatment in the process of exploitation or at the instant of brasses melting is considered. The p-T phase diagram of Cu-Zn system is suggested on the basis of analysis of the experimental data on thermodynamics of the liquid and solid alloys, pressure and composition of gas phase. The isobaric and isothermal sections of the phase diagram at temperatures of 400-1200°C and 650°C respectively are presented.
